A circle with radius of 6cm sits inside a circle with radius of 9 cm

What is the area of the shaded region

Answer: area of shaded region is 141.3 cm²

Step-by-step explanation:

We would assume that the shade region is the area between both circles. The area of the shaded region is the area of the outer circle - the area of the inner circle.

The formula for determining the area of a circle is expressed as

Area = πr²

Where

r represents the radius of the circle.

π is a constant whose value is 3.14

Considering the inner circle,

Radius = 6 cm

Area = 3.14 * 6² = 113.04 cm²

Considering the outer circle,

Radius = 9 cm

Area = 3.14 * 9² = 254.34 cm²

Area of the shaded region is

254.34 - 113.04 = 141.3 cm²
