Question 318452: 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°. Found 2 solutions by mananth, gsmani_iyer:Answer by mananth(16946) (Show Source):
You can put this solution on YOUR website! area of sector = angle /360 * pi*r^2
angle = 45
radius r= 8
..
area of sector = 45/360 *pi*8^2
Area =25.1 sq. in.
You can put this solution on YOUR website! The formula for area of the sector:
Here in your problem, theta = 45, r = 8.
Area of the sector:
= = 3.14 x 8 = 25.12 Sq.inches.
Area of the sector: Sq.inches. ANSWER
