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
Circumference = Diameter*pi So diameter = Circumference/pi = 32*pi/31 = 32

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
Since the circumference is Pi times the diameter then divide the circumference by Pi (3.14159) to get the diameter
