Radius of circle times 2, multiply that by pi (3.14 for easyish reckoning), and that's the circumference of a circle.
The circumference of an object is the distance around the outside or perimeter. Different formulae are used to calculate this depending on the shape.

What is the circumference of 23?
The circumference of a circle is given by the formula 2πr, where r is the radius of the circle. Since no radius is provided in this case, the circumference of 23 cannot be determined.
What is the distance around a circle with a diameter of 18 inches?
The distance around a circle is called the circumference. The formula for the circumference of a circle is C = πd, where C is the circumference, d is the diameter, and π is approximately 3.14159. For a circle with a diameter of 18 inches, the circumference would be C = π(18) = 56.5487 inches.
What is the formula for finding the area of base of a cylinder?
The circumference of a regular cylinder is the circumference of its circular face. C = pi * D (diameter of the cylinder) C = pi * 2r (or C = 2(pi)r)
Whats pi equal to?
Pi is a mathematical constant that is approximately equal to 3.14159. It is the ratio of a circle's circumference to its diameter.
How do you estimate the circumference?
Just look at it clearly keep a ruler and works doneTo estimate multiply diameter by 3 and add 15% ormultiply the diameter by 22 and divide that by 7.Just multiply the diameter by 3 for a good estimation.
What is the circumference of a loonie?
A circumference is 4
Is the radius one fourth of the circumference?
No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)No. It is circumference/(2*pi)
What is the circumference of a circle with the radius of 43?
Circumference = 2pi*r Circumference = 86pi
What is the formula of a circumference?
circumference=r2pi
Circumference in a sentence?

If circle circumference is 12 what is the radius?
Circumference = 12Diameter = Circumference/piRadius = Diameter/2 = circumference/(2 pi) = 1.9099 (rounded)
What definition of circumference?
The circumference is the distance around a closed curve. Circumference is a special perimeter.
What is the relationship between diamter and circumference?
circumference = pi*diameter or pi = circumference/diameter
Circumference circle of 8ft?
25.13 feet is the circumference. (diameter x pi = circumference).
Sentence for circumference?
The hole circumference was 12in. long >.<
How do you find a radius if you have the circumference?
You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).You divide circumference / (2 x pi).
