(62.8 / 3.14)/ 2 = 10.
10 is the radius
c=pi * d.
/pi= (to solve for d)
c/pi=d
c=62.8
pi=3.14
so substitute
62.8 / 3.14 = 20
d = 20
2r = d
/2 = /2
r = d/2
d = 20
substitute.
r=20/2 (solve 20/2)
r=10

What is the circumference of a circle with a radius of 100m?
Since the circumference of a circle is found by: C = 2 X Pi X r , where Pi can be rounded to 3.14 C = 2 x 3.14 x 100 C = 628 m The circumference can also be found by using the diameter: C = Pi X d, where d = 2r
