To find the area of the slice of pie, you will represent the part of the pie as 37/360 because this is the fractional part that was cut. Multiply this by the total area of the circle to get the area of this one slice.
A = 37/360 x pi x r^2 37/360 x 3.14 x 17.5^2 A = 98.8 square feet
The approximate area of the slice was 98.8 square feet. That is one big pie!!
