Answer:
Option d is correct answer.
Step-by-step explanation:
Given in the picture is a circle with a sector quadrant circle.
WE have the formula for the sector of a circle
If angle of the sector is x
then we have
area of the sector =[tex]\frac{x}{360} (\pi r^2)[/tex]
Here x=central angle = 90 and r = radius = 8
Substitute to get
[tex]\frac{90}{360} (\pi )(8^{2} )\\=16\pi[/tex]
