If it's a circle, then it's pi*diameter or 2*pi*radius.
If it is an ellipse, the circumference (perimeter) is an infinite series with an approximation based on its eccentricity (which for a circle is zero).

To calculate the true lengths for bend allowances and circumferences, you first need to determine the bend radius and the material thickness. The bend allowance can be calculated using the formula: Bend Allowance = (π/180) × Bend Angle × (Radius + (Material Thickness/2)). The true length of the bend can then be found by adding the straight lengths of the sections on either side of the bend to the bend allowance. For circumferences, use the formula: Circumference = 2 × π × Radius.
The formula for finding probability depends on the distribution function.
No because the formula for finding the area of an oval, which is an ellipse, is quite different
There is no formula for this. You have to measure the volume.
The formula for finding area or mass of a cylinder is pi x radius^2density=massxvolume
Because it was found that there was a direct relationship between the radii (or diameters) of circles and their circumferences.

There isn't a formula for finding joules. It is a way for finding a force or giving an example.
An arc
They are circumferences
the formula for finding the area of an ellipse is add it then multiply and subtract that is the final
The formula for finding the perimiter of a rectangle is add up all of its sides
There is no formula for finding anything - except perhaps the inevitable "where was it when you last saw it?"
