Question

Find the area of a 60 degree sector with radius 10.

Select one:
a. 209
b. 52.3
c. 188
d. 314

Answer 1

(b) 52.3

Explanation:

Given that,

Radius, r = 10

Angle,
`\theta=60^(\circ)`

We need to find the area of the sector. The formula for the area of the sector is given by :

`A=(\theta)/(360)\pi r^2\\\\=(60)/(360)* (22)/(7)* (10)^2\\\\=52.3\ \text{unit}^2`

Hence, the correct option is (b).
