If you're talking about a circle, then the perimeter is more often called the "circumference".
If you know the circumference, then Diameter = (circumference) divided by (pi).
(Pi) is approximately 3.14159 26535 89792 . But if you use (22/7), you're off by less than 1/10th of 1 percent.

How do you find the perimeter of a diameter of 700m?
The formula for finding the perimeter (circumference) of a circle based on its diameter is C = πd. so if the diameter is 700m, you multiply that by π (3.14) for a circumference of 2,198m.

What is the perimeter of a 6.2 radius circle?
There is no such thing as the perimeter of a circle. The circumference, however, is 12.4*pi (since the formula is pi*diameter)
What is formula of perimeter of semi circle?
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)
How can convert area to diameter?
To convert area to diameter for a circle, you can use the formula ( A = \pi r^2 ), where ( A ) is the area and ( r ) is the radius. First, solve for the radius by rearranging the formula: ( r = \sqrt{\frac{A}{\pi}} ). The diameter ( d ) is then found by doubling the radius: ( d = 2r ). Thus, the formula to convert area to diameter is ( d = 2\sqrt{\frac{A}{\pi}} ).
What is the formula for the perimeter of a semicircle?
If you are given the diameter 'D' of the circle: the full circumference is (pi times D) the perimeter of the semicircle is half this plus the diameter Therefore: Pi x D /2 + D
