Question

What’s the circumference of a circle with a diameter of 14 feet

Answer 1

About 44ft. You have to use the equation C=2piR where R is radius. Since radius is half diameter this would be R=7.

C=(2)pi(7)
C=14(pi)
C= ~43.98

Answer 2

C = 14pi or approximately 43.96 ft

Explanation:

The diameter is 14

Circumference is given by

C = pi*d

C = pi*14

C = 14pi

We can approximate pi by 3.14

C = 14*3.14 =43.96
