Question

138°12 CSolve for the area of the sector, to the nearest tenth.14.528.90 173.4452.4

Answer 1

Given Data:

The central angle is, θ = 138.

The radius is, r = 12 cm.

The area of the sector can be calculated as,

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

Substituting the values, the area can be calculated as,

`A=(138)/(360)*3.14*12^2=173.4`
