Calculate the shaded area of the square below if the side length of the hexagon is 6 cm. The side length of the four unshaded small squares is 4 cm each. Bricks is an AI spreadsheet that does all your spreadsheet tasks for you using natural language prompts. By using shaded areas strategically, you can make your data more actionable and insightful, no matter your field.
We can observe that the outer rectangle has a semicircle inside it. From the figure we can observe that the diameter of the semicircle and breadth of the rectangle are common. To find the area of the shaded region of acombined geometrical shape, subtract the area of the smaller geometrical shapefrom the area of the larger geometrical shape. To find the area of shaded region, we have to subtract area of semicircle with diameter CB from area of semicircle with diameter AB and add the area of semicircle of diameter AC. The remaining value which we get will be the area of the shaded region. The most advanced area of shaded region calculator helps you to get the shaded area of a square having a circle inside of it.

So finding the area of the shaded region of the circle is relatively easy. All you have to do is distinguish which portion or region of the circle is shaded and apply the formulas accordingly to determine the area of the shaded region. Find the area of the shaded region in terms of pi for the figure given below. The area of the circular shaded region can also be determined if we are only given the diameter of the circle by replacing “$r$” with “$2r$”. Afterwards, we can solve for the radius and central angle of the circle.
The Step-by-Step Process
From the figure we can see that the value of the side of the square is equal to the diameter of the given circle. Area is basically the amount of space occupied by a figure. The unit of area is generally square units; it may be square meters or square centimeters and so on. The following diagram gives an example of how to find the area of a shaded region. These lessons help Grade 7 students learn how to find the area of shaded region involving polygons and circles. Let’s see a few examples below to understand how to find the area of a shaded region in a square.
Shaded Area Formula:
- Or subtract the area of the unshaded region from the area of the entire region that is also called an area of the shaded region.
- Excel is a staple in the toolkit of many professionals, from analysts to project managers.
- The semicircle is generally half of the circle, so its area will be half of the complete circle.
- See this article for further reference on how to calculate the area of a triangle.
- At the same time, we will discuss in detail how to find the area of the shaded region of the circle using numerical examples.
- For example, you might want to emphasize a promotional period in sales data or highlight a significant change in trend.
Calculate the area of the shaded region in the right triangle below. In summary, adding a vertical shaded area to your Excel graph can make a world of difference in how your data is perceived. By following the steps outlined here, you can create informative, visually appealing graphs that highlight the most important aspects of your data.
We are given the area and the radius of the sector, so we can find the central angle of the sector by using the formula of the area of the sector. We are given the area and central angle of the sector, so we can find the radius of the sector by using the formula of the area of the sector. To find the area of the shaded region of a circle, we need to know the type of area that is shaded. It is also helpful to realize that as a square is a special type of rectangle, it uses the same formula to find the area of a square. The area of a triangle is simple one-half times base times height.
- The second way is to divide the shaded part into 3 rectangles.
- Often, these problems and situations will deal with polygons or circles.
- Then add the two areas together to get the total area of the shape.
- Many other more complicated shapes like hexagons or pentagons can be constructed from a combination of these shapes (e.g. a regular hexagon is six triangles put together).
- Also, in an equilateral triangle, the circumcentre Tcoincides with the centroid.
- Let R and r be the radius of larger circle and smaller circle respectively.
How To Determine the Area of a Segment of a Circle
You can also find the area of the shaded region calculator a handy tool to verify the results calculated in the above example. Try the free Mathway calculator andproblem solver below to practice various math topics. Try the given examples, or type in your ownproblem and check your answer with the step-by-step explanations. Calculate the area of the shaded region in the diagram below. This is a composite shape; therefore, we subdivide the limefx diagram into shapes with area formulas. The area of the shaded part can occur in two ways in polygons.
Let’s see a few examples below to understand how to find the area of the shaded region in a rectangle. Let’s see a few examples below to understand how to find the area of a shaded region in a triangle. As stated before, the area of the shaded region is calculated by taking the difference between the area of an entire polygon and the area of the unshaded region. The area of the shaded region is the difference between the area of the entire polygon and the area of the unshaded part inside the polygon. The area of the shaded region is most often seen in typical geometry questions. Such questions always have a minimum of two shapes, for which you need to find the area and find the shaded region by subtracting the smaller area from the bigger area.

So, its area will be the fourth part of the area of the complete circle. We can observe that the outer right angled triangle has one more right angled triangle inside. Similarly , the base of the inner right angled triangle is given to be 12 cm and its height is 5 cm. So, the area of the shaded or coloured region in a figure is equal to the difference between the area of the entire figure and the area of the part that https://www.forex-reviews.org/ is not coloured or not shaded.
Still, in the case of a circle, the shaded area of the circle can be Forex harmonics an arc or a segment, and the calculation is different for both cases. The grass in a rectangular yard needs to be fertilized, and there is a circular swimming pool at one end of the yard. The amount of fertilizer you need to purchase is based on the area needing to be fertilized. This question can be answered by learning to calculate the area of a shaded region.
By drawing the horizontal line, we get the shapes square and rectangle. The ways of finding the area of the shaded region may depend upon the shaded region given. For instance, if a completely shaded square is given then the area of the shaded region is the area of that square. When the dimensions of the shaded region can be taken out easily, we just have to use those in the formula to find the area of the region. We can observe that the outer square has a circle inside it.
The calculation required to determine the area of a segment of a circle is a bit tricky, as you need to have a good grasp of finding the areas of a triangle. The picture in the previous section shows that we have a sector and a triangle. The area of the circle enclosed in a segment or the shaded region inside the segment is known as the area of the segment of a circle. If we draw a chord or a secant line, then the blue area as shown in the figure below, is called the area of the segment.
