Question

The circumference of a circle that has a diameter of 8'-6" is

A) 64'-6"
B) 24.5'
C) 8.5'
D) 26.7'

Answer 1

Answer: 26.7 feet (choice D)

Work Shown

d = diameter

d = 8' 6" = 8 feet + 6 inches = 8.5 feet

C = circumference

C = pi*d

C = 3.14*8.5

C = 26.69

C = 26.7 feet

This is the approximate perimeter or distance around the circle. It's the amount of fencing needed to enclose the circle.

The value is approximate because pi = 3.14 is approximate.
