The formula for finding the circumference of a circle is:
circumference = pi * diameter
So if we rearrange that, to find the diameter, we have to divide the circumference by pi.
733/pi = 233mm (3 sig fig)
The diameter is therefore 233mm

Circumference is Pi x Diameter so do Circumference divided by Pi to get the diameter :)
diameter = circumference/pi
circumference = diameter * pi. Therefore, diameter = circumference ÷ pi.
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference = pi*diameter So diameter = circumference/pi = 1.59 units
