Working Out Diameter
2016-10-15 22:59:36 · answer #2 · answered by ? 4 · 0⤊ 0⤋
ok first off there is no such thing as an outside diameter. The diameter is the distance from one edge of a circle to the other in a straight line. Circumference is the distance around the circle.
circumference = diameter x pi
or
diameter = circumference/pi

The equation for the circumference of a circle is 2*pi*r (r is the radius of a circle, pi is the constant 3.142).
The diameter of a circle is twice the radius (or 2*r) therefore the circumference of a circle is also pi*d (d is the diameter).
So if you measure the circumference and divide it by pi, then you get the diameter.
Hope this helps.

Divide it by pi
circ. = pi * diameter

there's a silly rhyme our teacher taught us once to remember this kind of thing...
fiddle dee dum fiddle de dee, a ring round the moon is pi times d, and if a hole you want repaired then you must use pi r squared.

circumfrence divided by pye * 2 should give diameter.
