The circumference of a circular garden....!

The circumference of a circular garden is 94.2 feet. What is the diameter of the garden? Use 3.14 for PIE (Mathematical Term) and do not round your answer.

c = 2pi(r)

94.2 = 2(3.14)r

94.2 = 6.28r

15 = r

d = 2r

d = 2(15) = 30 ft

2*pi*r=circumference
6.28*r=94.2
r=15
d=2r=30
