Question

Find the area of the minor sector
1 r=9cm,tita=70​

Answer 1

The area is 49.5 cm^2

Explanation:

To find the area of the sector, we are going to use the formula for the area of a sector

Mathematically, we have this as;

A = theta/360 * pi * r^2

r = 9 cm and theta = 70

Substituting these values

A = 70/360 * 3.142 * 9^2

A = 49.5 cm^2
