BeauIf you have an n-sided regular polygon, given the perimeter (P), the formula for diameter (D) is:
D = P / (n * sin(π / n))
For a circle, replace n with the biggest real number you want to, but the bigger the number the more accurate the calculation will be;
circumference (C) = P
D = C / (n * sin(π / n)); n -> Infinity

How do you find the perimeter from the diameter?
The perimeter or circumference of a circle = diameter times pi
What is the perimeter of a circle if the diameter is 20 ft?
The perimeter is the diameter times pi. So the perimeter is 20pi ft
How do you find the perimeter of a circle with just the diameter?
the perimeter is 3 times as long as the diameter Example: if my diameter is 7 inches long my perimeter is 3 times as much so it is 21 inches long
How do you Find The Perimeter of a Circle With an diameter?
Multiply the diameter by pi.
If a diameter of the semicircle is 14cmfind its perimeter?
Perimeter = Circumference/2+Diameter Perimeter = (pi*14)/2+14 = 35.99114858cm or 36cm correct to two significant figures.
