Question

Tina made a 9-inch apple pie, which she cut into 8 slices. Tina and 2 of her friends each ate a piece of pie. what is the approximate area of the
remaining pie?

A. 18 in^2
B. 24 in^2
C. 40 in ^2
D. 159 in^2

Answer 1

9" = the diameter
4.5" = the radius
area of a circle = π * r^2
area of pie = 4.5^2 * π
8-3 = 5 so 5/8 remaining
5/8 * 4.5^2 *π
this is equal to 39.7 which rounds to 40"^2
