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.

What is the formula for perimeter is shape is a circle?
The perimeter is equal to Pi times the diameter.
Perimeter of a circle formula?
2*pi*radius or pi*diameter
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
How do you convert perimeter to diameter?
perimeter / pi (3.14) = diameter
What is the formula for an octagon?
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
What is the formula for perimeter is shape is a circle?
The perimeter is equal to Pi times the diameter.
Formula for perimeter of a circle?
Circumference or perimeter = 2*pi*radius or pi*diameter
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.
Perimeter of a circle formula?
2*pi*radius or pi*diameter
What is the formula for finding perimeter of a circle?
The formula for the circumference of a circle is pi * diameter or (2 radius.)
How do you convert perimeter to diameter?
perimeter / pi (3.14) = diameter
What is the formula for finding the perimeter of a semicircle?
Half the Circumference + the DiameterCircumference of a circle = pi X d ,so perimeter of a semi-circle = (3.142 X Diameter) + Diameter
What is the formula for an octagon?
There is no formula for an octagon. There are formulas for figuring out different aspects of an octagon, such as its perimeter, diameter, etc.
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)
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
What is the perimeter of a circle with a diameter of 8 inches?
The perimeter of a circle is called its circumference. The formula for calculating the circumference is: C = πd (pi x diameter).In this case, this would be 8 in. x 3.14... or about 25.13 inches.
