Find the area of the shaded sector. Leave your answer in terms of π.

IgorLugansk [536]

Answer:

16π m2

Step-by-step explanation:

The area of a sector (A) is given by:

$A=\frac{\theta}{360}* \pi r^2$

Where

$\theta$ is the angle of the sector

r is the radius of the circle

We can see that the angle of the sector is 90, and the radius of the circle is 8. Plugging these into the formula, we get:

$A=\frac{90}{360}* \pi (8)^2\\A=\frac{1}{4}* \pi (64)\\A=16 \pi$

The area is 16π m2
