Question

A sector of a circle has a central angle of 150∘. Find the area of the sector if the radius of the circle is 17 cm.

Answer 1

378.3
`cm^(2)`

Explanation:

a =
`\pi`
`r^(2)` for a whole circle, but we only want the area for part of a circle

a =
`(150)/(360)`
`\pi`
`17^(2)`

a = 378.3
`cm^(2)` rounded to the nearest tenths place
