Question

An apple pie has a 12-inch diameter and the angle of one slice is 60 degrees. What is the area of that slice of pie? Use 3.14 for pi.
14.13 square inches
75.36 square inches
3 pi square inches
18.84 square inches
0.52 square inches

Answer 1

The area of the slice is given by:
 A = k * pi * r ^ 2
 Where,
 r: Apple pie radius
 k: relationship of arcs
 We have then:
 A = (60/360) * 3.14 * (12/2) ^ 2
 A = 18.84 in ^ 2
 Answer:
 The area of that slice of pie is:
 18.84 square inches
