Question

Find the area of the sector of the disk of radius r=15 ft and with arc length s=13 ft.

When I did it it came out to .8666667, is that right or do I have to do 1/(13)(15) to get 1.15384571.

circumference = 2P(15) = 30π
fraction of arc over circumference = 13/30π = .137934

whole area = P(15^2) = 225π

sector = .137934(225π) = 97.5 ft^2
