329.7 cm²

Explanation:

Step 1:

To find the area of the shaded region, we will subtract the smaller area from the larger area.

Step 2:

Area of Circle = π
*

Where, r= radius of circle

π = 3.14

Here Larger circle area (A) = π
* 11
* 11 ( r = 11 cm)

= 379.94 cm²

Smaller circle area (a) = π
* 4
* 4 ( r = 4 cm)

= 50.24 cm²

Step 3:

Shaded Area = A - a

= 379.94 - 50.24

= 329.7 cm²

A circle with radius of 4 cm sits inside a circle with radius of 11 cm what is the-example-1
