Question 1 of 5

Answer 1

Formula for the circumference of a circle:

C = πd    or     C = 2πr      

[C = circumference    π(pi)       d = diameter        r = radius(half the diameter)]

You know:

d = 5 feet        

and you're using 3.14 for π, so substitute/plug it into the equation

C = πd

C = (3.14)(5)

C = 15.7 feet       Your answer is B
