Question

Find the exact circumference of a circle with the given radius.

7 feet

C =

a. 7π ft.
b. 14π ft.
c. 27π ft.

Answer 1

The formula in computing the circumference of a circle is:

C = 2πr
Where: r = the radius of the circle

Substituting the given measurement of radius to the formula:
C = 2 (π) (7 feet)
C = 14π feet
Therefore, the circumference of the circle is 14π ft.

 

Answer 2

the answer is 14 pi ft
