When the shape is a circle, then the perimeter is called"circumference".The circumference IS the perimeter of a circle.

The circumference of a circle is the same as the perimeter of a circle, so the perimeter and circumference would both be 3 ft.

Its perimeter is half of its circumference plus its diameter

The perimeter or circumference of a circle = diameter times pi

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.

Circumference ("perimeter") of a circle = (pi) x (diameter of the circle)

The equivalent of a "perimeter" in a circle is actually called its circumference. To get the diameter, just divide the circumference by pi.

-- 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).

Its perimeter is half of its circumference plus its diameter

The perimeter or circumference of a circle = diameter times pi

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.

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.

A circle does not have a perimeter, but it has a circumference, which is pretty much the same thing. To find the circumference, multiply pi(3.14) times the diameter which is the distance across the center of the circle. I hope this helped

As for example when constructing a round-about on a road you'll need to know its perimeter which is the circumference of a circle.

The perimeter of a circle is called the circumferenceTo find the circumference of a circle you do 2 times pi times radiusC = 2 * 3.14159 * 7 = 43.98inchesSince this is a half circle you have to take half of the circumference...you answer is 21.99inches
