Question

Find the area of the sector:
A=
yd? (Round to one decimal place)
210°
16 yd

Answer 1

469.1 yd²

Explanation:

The area (A) of the sector is calculated as

A = area of circle × fraction of circle

= πr² ×
`(210)/(360)`

= π × 16² ×
`(21)/(36)`

= 256π ×
`(7)/(12)`

≈ 469.1 yd² ( to 1 dec. place )

Answer 2

469.1 yd^2 because I plugged it into the equation and I got that as the answer
