Diameter = Circumference/pi
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
circumference/pi = diameter
11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
If you have only the diameter to get the circumference you have to multiply the circumference by pi: 3.14
Diameter = Circumference/pi
diameter = circumference/pi
You cannot find the diameter of something from its circumference unless it is a circle and, in that case, diameter = circumference/pi
Circumference = Pi * diameter
Divide the circumference by Pi to find the diameter.
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
Diameter = radius * 2 Circumference = pi * diameter.
Circumference: Diameter x pi (3.1415926535897932384...)
circumference/pi = diameter
diameter*pi = circumference
Diameter = circumference/pi
11 is a good approximation of the diameter. If the circumference is 35, the actual diameter is about 11.14 (35/3.1416).
