Circumference = 2*pi*r = 12.566 cm (approx)
Something that goes around
The circumference is Pi x r x r.... In THIS case it's .25 x .25 x Pi... which equals 0.19634375
Circumference = 2*pi*r Circumference = 2*3.14*25 => 157 inches

Circumference = 2*pi*r = 12.566 cm (approx)
C=2(pi)(r) therefore if r equals 3.20 then C=20.1061929

Circumference = r x pi and d = 2r. So, r = d/2 = 6/2 = 3ft and Circumference = 3ft x 3.14 = 9.42.
9. Circumference equals 2 times Pi times the radius. C=2(pi)r. "r" for radius. So if your circumference is 18 times pi, then you do 18 divided by 2, which gives you a radius of 9.
(20 X 20) X 3.14 = 1256 yards Pi = 3.14 Circumference = 1256yd
The circumference of a circle is its perimeter, or the distance around it. It equals 2(pi)r or pi*d, where r is the radius, d is the diameter and pi is 3.14...
