Measure the diameter (the width) and multiply it by Pi.
40.8407045
Multiply the diameter by pi, and the answer will be the circumference.
circumference = 84*pi
Divide the circumference by pi (~3.14) to get the diameter.
Circumference of a circle = 2*pi*radius or pi*diameter.
circumference of a circle = 2*pi*radius or pi*diameter
It is important becasue the equation for the circumference is 2 times the ratio times pi.
Circumference = pi*85 = 267.035 units of measurement to 3 decimal places
Circumference of a circle = 2*pi*radius or pi*diameter
No way of telling, it'd all depend on the profile of the rim.
