A circle with a radius of 3cm sits inside a circle with a radius of 11cm.

what is the area of the shaded region?

Round the final answer to the nearest 100.

Area of shaded region = 351.68 cm²

Step-by-step explanation:

Area of a circle = πr²

where r = radius = 3.14

Area of bigger circle = 3.14 * 11²

= 3.14 * 11 * 11

= 379.94cm²

Area of smaller circle = 3.14 * 3²

= 3.14 * 3 * 3

= 28.26cm²

Area of shaded region = Area of bigger circle - Area of smaller circle

= (379.94 - 28.26) cm²

= 351.68 cm²
