diameter x pi
15.92mm
The circumference of a circle with a diameter of 31.8mm is about 100mm (99.990265mm)
36/pi = 11.4591559 inches
Circumference equals Diameter times Pi, OR Diameter equals (Circumference)/(Pi). In this case, Diameter equals (130mm)/(Pi or 3.14159) equals 41.38mm
circumference/pi = diameter
diameter x pi
The diameter is 14 / 3.141592654 = 4.4563384 inches.
15.92mm
The formula is pi multiplied by the diameter
The volume in liters of a cylinder with a diameter of 2000mm and a depth of 100mm is: 314 liters.
The volume in liters of a 100mm long by 50mm diameter cylinder is: 0.196 liters.
circumference = pi*diameter so diameter = circumference/pi = 19.1 metres.
If the diameter is known, don't bother measuring the circumference.Simply multiply the diameter by 'pi'.
You get it by multiplying the radius by 2 or dividing circumferance by 3
The circumference of a circle with a diameter of 31.8mm is about 100mm (99.990265mm)
you multiplay the radius by 2 or divide the circumferance by 3
