Question 325377: A circle has a radius of 8 inches. Find the area of a sector of the circle if the sector has an arc that measures 45°. Answer by checkley77(12844) (Show Source):
You can put this solution on YOUR website! A=PIR^2
A=3.14*8^2
A=3.14*64

BECAUSE AN ARC OF 45 DEGREES IS 45/360=.125 OF THE AREA.
THEN:
.125*200.96=25.12 INCHES^2
