Question

Chris ate 1/8 of a banana cream pie with a 14 inch diameter. What is the area of the remaining portion of the pie? Round to the nearest tenth. Use 3.14 for pi.

Answer 1

Area of a circle is pi x radius squared.

If we use 3.14 for pi, and the Diameter is 14 so that radius will be 7 (half of diameter), this means we have 3.14 x 7 squared = 153.86.

Total area of pie is 153.86.

If 1/8 was eaten that means 7/8 are left.

153.86/8= 19.23

19.23 x 7 = 134.6 to the nearest tenth..
