Question

A giant pie is created in an attempt to break a world record for baking. The pie is shown below:

What is the area of the slice of pie that was cut, rounded to the nearest hundredth?

a. 78.13 ft2
b. 82.43 ft2
c. 86.31 ft2
d. 91.98 ft2

Answer 1

That "piece of the circle" is called a sector of the circle.

The area of a sector of a circle =

n/360 x (pi)(radius)^2

where n = number of degrees in the central angle of the circle

Answer 2
