Question

In circle M with m Round to the nearest hundredth.

Answer 1

We know that the area of a sector is given by:

$A = \dfrac{\pi r^2\alpha}{360}$

Where α is the angle in degrees and r is the radius. We have:

• r = 9
• α = 82°

Evaluating:

$A = \dfrac{\pi r^2\alpha}{360} = \dfrac{\pi(9)^2\cdot 82}{360} = 57.96\ u^2$
