How do you calculate the area of shaded regions?
How to Find the Area of a Shaded Region?
- Firstly, find out the area of the large geometrical shape or outer region.
- Then, find the area of the small geometrical shape or inner region of the image.
- Finally, subtract an area of the small geometrical shape (entire region) from the large area of the small geometrical shape (shaded region).
How do you find the sector of a shaded area?
To find the area of a sector of circle using online calculator, follow the steps below:
- Go to the Sector Area Calculator.
- Select the set of parameters that is given.
- Enter the given values in the respective input boxes. i.e., radius, angle, etc.
- Press the Calculate
How can we find the area of the shaded part?
- GFE + x + 2y = HGFEDMN
- GFE = z + 2y
- j + 2z = HILDMN
- j + 2x = ACLMEGNI
What is the formula for finding the shaded sector?
- The area of a circle is calculated as A = πr². This is a great starting point.
- The full angle is 2π in radians, or 360° in degrees, the latter of which is the more common angle unit.
- Then, we want to calculate the area of a part of a circle, expressed by the central angle.
How did you find the area of the shaded region?
Usually, we would subtract the area of a smaller inner shape from the area of a larger outer shape in order to find the area of the shaded region. If any of the shapes is a composite shape then we would need to subdivide it into shapes that we have area formulas, like the examples below.
What is the area of shaded region?
What is the area of the shaded region? The area of the shaded region is the difference between the areas of the rectangle and the square.
How do you find the shaded area of a shape?
Find the area of the shaded region by subtracting the area of the small shape from the area of the larger shape. The result is the area of only the shaded region, instead of the entire large shape.

What is the area of a shaded 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.
How to find the area of a shaded region in a triangle?
Let’s see a few examples below to understand how to find the area of a shaded region in a triangle.
How long are the 4 unshaded squares?
The side length of the four unshaded small squares is 4 cm each.
Problem
Two circles, with radii 2 and 1 respectively, are externally tangent (that is, they intersect at exactly one point). An outer circle is tangent to both of these circles. Find the area of the shaded region.
Strategy
Our usual strategy when presented with complex geometric shapes is to partition them into simpler shapes whose areas are given by formulas we know.
