2 x pi x radius = circumference 18.5 inches times 2 times 3.15159 is about 116.239 inches.
The radius of a circle whose circumference is 40pi is 20 units.
The circumference of a circle is its diameter times pi, which is the same as twice the radius times pi.A = 2r (pi)In this instance, the circumference is 32(pi) inches(about 100.53 inches)
The radius is: 21.98/2*3.14 = 3.5 inches
The radius of a circle whose circumference is 36 pi (113.1) is: 18 (circumference divided by Pi divided by 2 = radius)
