Last updated over 1 year ago
22 questions
The area for the sector of a circle is found by using the formula

A = π • r² • m/360

r is the radius of the circle.

m is the measurement of the angle making the sector.

For the first problem below #3A

It would be

π • 4² • 53/360

And that would equal 7.4 ft²
