Question

Find the area of this sector

Answer 1

0.0146607657 rad m

Answer 2

7π mm²

Explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² ×
`(280)/(360)` ( r is the radius )

= π × 3² ×
`(28)/(36)`

= 9π ×
`(7)/(9)` ( cancel the 9's )

= π × 7

= 7π mm²
