Question

Find the area of the sector with a central angle of 60° and a radius of 5 inches. Round to the nearest tenth

Answer 1

area of sector = 60 * 22*5*5/360*7
= 550/42
= 13.09

Answer 2

Hey!!
I will definitely help
We know that,
Central Angle = 60 degrees =
$\pi \div 4$
Radius = 5 inches
Then,
Area = 1/2r^2theta
1/2*5*5*
$\pi \div 4$
12.5*pi /4
12.5*22/7*1/4
=137.5

It is nearest to 140........
So the answer is 140





:-) hope it helps
