Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.
Diameter = Circumference/pi
diameter = circumference/pi
using the formula circumference=diameter X pi: circumference=diameter X pi circumference/pi=diamter X pi/pi circumference/pi=diameter therefore, diameter=circumference/pi diameter=12mm/3.14 diameter=3.821mm
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
The circumference of a 13.5 diameter circle is: 42.41(diameter x pi = circumference).
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
Circumference = diameter(pi) so divide the circumference by pi to get the diameter.
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
