The perimeter P is the distance around a given two-dimensional object. The word perimeter is a Greek root meaning measure around, or literally "around measure". P = pi times d d = diameter The circumference C is the distance around a closed curve. Circumference is a kind of perimeter. C = pi times d d = diameter In geometry, a diameter of a circle is any straight line segment that passes through the center of the circle and whose endpoints are on the circle. The diameters are the longest chords of the circle. In more modern usage, the length of a diameter is also called the diameter. In this sense one speaks of "the" diameter rather than "a" diameter, because all diameters of a circle have the same length, this being twice the radius. Conversion perimeter C to diameter d and back: C = pi times d d = C / pi

Given the diameter (D) and the number of sides (n) of a regular polygon, the perimeter (P) is:
P = Dn * sin(π / n)
When using the formula for circumference (C), assume the circle has a number of sides that approaches infinity;
C = Dn * sin(π / n), as n -> Infinity

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.
How do you convert perimeter to diameter?
perimeter / pi (3.14) = diameter

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 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 formula to convert perimeter to diameter?
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 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
