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
If a circle has a circumference of 8 the diameter is: about 2.546 (circumference divided by pi = diameter).
The circumference of 1.5 diameter is: 4.712
Circumference = Pi * diameter

Diameter = Circumfrence/pi = 13/pi = 4.14 cm (approx)
The circumference of a circle if its radius is 13cm is: 81.68 cm
Circumference of the circle: 13*pi = 40.841 cm rounded up to 3 decimal places
Something that goes around
Radius = about 13cm Diameter = about 26cm
It is: 2*pi*13 = 81.681 cm
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
