The perimeter of a circle is the circumference.
If you mean the circle is drawn around (and touches the 4 corners of) a square, and you know the perimeter of the square, you divide the square's perimeter by 4, do pythagorean's theorem on the 2 sides (legs) to find the hypotenuse, and that hypotenuse will be the diameter of the circle. You then multiply that diameter you get by pi to get the circumference.

How do you find the perimeter when circumference is given?
When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.
How do you find the perimeter if you already know the circumference of a circle?
The circumference of a circle is the length of the circle's perimeter.
What is the equation to find the perimeter of a circle?
Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)
What is the value and perimeter if the circumference of a circle if it is 3 ft?
The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.
How do you find the diameter of a circle with the perimeter?
The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.
How do you find the area of a circle when you are only given its perimeter?
The Perimeter of a circle is it's circumference. And the circumference is the diameter times pi. So to find the area, divide the circumference by pi, and get the diameter. Then divide the diameter by 2, to get the radius. Then multiply the radius times itself, and multiply that by pi.
How do you find the perimeter of a semi circle with a diameter of 12mm?
-- Find the circumference of a full circle with a diameter of 12 mm.-- The perimeter of the semi-circle is(1/2 the circumference of the full circle) + (the diameter).
How do you find the perimeter for a semi circle?
Its perimeter is half of its circumference plus its diameter
How do you find the perimeter from the diameter?
The perimeter or circumference of a circle = diameter times pi
How do you calculate perimeter of circle given the radius?
Well, you never have a perimeter for a circle, you have to find the circumference. The perimeter is the length of the borders of a shape, and a circle has no border. The formula for circumference is, C= Pi multiplied by the diameter. To find the diameter just multiply the radius by two. Pi is a never ending number, but you should use it as 3.14 times the diameter
How do you find the length of perimeter or circumference of a circle?
Since pi is the ratio of a circle's circumference to its diameter, multiply the diameter by pi (about 3.14159) to get the circumference.
How do you find the DIAMETER if given the circumference OF A CIRCLE?
Diameter of a circle = circumference/pi
