What is the area of the sector bound by the center of the circle and arc CD in the circle below?

The formula for the area of a sector is: PI x r^2 x (X/360) where X is the degrees of the sector and r is the radius
r is given as 15 feet and X is given as 45 degrees.
The formula is: PI x 15^2 x (45/360) = 88.3125 square feet
Round the answer as needed.
Area of circle = 3.14 x 15^2
= 3.14 x 225
= 706.5
706.5 x
--------- = -----------
360 45
Cross Multiplying
360 * x = 45 * 706.5
360x = 31,792.5
x = 88.3125
answer
area of the sector = 88.3125 ft^2
