Find the area of the square

Find the area of the circle

Subtract the area of the circle from the area of the square.


area of square = 10 x 10 = 100 sq. Cm

Area of circle = pi x r ^2 = 3.14 x 5^2 = 78.5 sq. Cm


area of shard region = 100 - 78.5 = 21.5 cm^2

If the shaded region is the circle (which it is),

The area of it is 78.5cm²

You can find the area of a circle by using the formula: pi • radius squared

In this case, the question states to use 3.14 for pi so our equation would look like:

3.14 • 5 • 5 (5 squared is same as 5 times5)

And that is how you get 78.5cm²
