Question

In circle E with m DEF 36 and DE = 3 units find area of

sector DEF. Round to the nearest hundredth.
E

Answer 1

A ≈ 2.83 units²

Explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² ×
`(36)/(360)`

= π × 3² ×
`(1)/(10)`

=
`(9\pi )/(10)`

≈ 2.83 units² ( to the nearest hundredth )
