The perimeter is equal to Pi times the diameter.
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
to find the perimeter of a circle you simply do this (pi x D )
The perimeter of a circle has the formula 2πr. Therefore the length of a semi circle is πr. But the perimeter of a semi circle also includes the diameter which is 2r. Therefore the perimeter of a semi circle = πr + 2r = r(π + 2)
If it's a circle, then the formula is ╥d (Pi (3.14) times the diameter)
The formula for the perimeter of a shape depends on the shape. It is the sum of the lengths of all the sides that enclose the shape.

If you want to enclose a certain area, the shape that does it with the shortest perimeter is a circle.
Add up the lengths of all the sides. (Same for any shape [except a circle])
There is no specific formula for a sector of a circle. There is a formula for its angle (at the centre), its perimeter, its area.
The formula for the circumference of a circle is pi * diameter or (2 radius.)
There are different formula for: Height, Area, Perimeter, Angle, Length of Median Radius of inscribed circle Perimeter of inscribed circle Area of inscribed circle etc.
The answer will depend on what the formula is for: the perimeter or area of the segment.
There are different formulae for the perimeter, area or other aspects of each shape. Furthermore, the formula may well depend on what information is available to you.
