Question

A sector of a circle with radius 8 cm has an angle measure of 120°. What is the area of the sector to the

nearest tenth of an inch?

Answer 1

64.9 cm

Explanation:

Area of a sector is

`A=\pi r^(2) ((angle)/(360) )`

r is 8 and the angle measure is 120

`A=\pi 8^(2) ((120)/(360) )\\A=62\pi ((120)/(360) )\\A=64.93`

or 25.5 inches ? The question has the radius measured in cm, but asks for the answer in inches. So depending on how the actual question is worded, the answer will change.

64.9cm is equal to about 25.5 inches

Answer 2

125.66cm
