Question

What is the area of the figure?

Answer 1

`50.2 \: {units}^(2)`

Explanation:

Area of the shaded region = Area of exterior circle with radius (3 +2 = 5) units - Area of interior circle with radius 3 units

`= \pi {(5)}^(2) - \pi {(3)}^(2) \\ \\ = \pi( {(5)}^(2) - {(3)}^(2) ) \\ \\ = 3.14 * (25 - 9) \\ \\ = 3.14 * 16 \\ \\ = 50.24\\ \\ \approx 50.2 \: {units}^(2)`
