An apple pie with a circumference of 28.26 inches is cut into 6 equal-sized pieces. Two pieces of the pie are eaten. What is the area of the pie that is left? Select the correct answer. Use 3.14 for π.
Accepted Solution
A:
C = πd d = C / π d = 28.26 / 3.14 d = 9 in
but r = d/2 = 9/2 = 4.5 in
A = π r^2 = 3.14 x (4.5^2) = 3.14 x 20.25 = 63.585
divided into 6 equal so 63.585 / 6 = 10.5975
but ate 2, so there are 4 pieces left 4 x 10.5975 = 42.39
answer the area of the pie that is left is 42.36 in^2
