How do you calculate the circumference if you know the diameter?

Circumference is equal to 2 times pi (3.1416) times one half of the diameter (the radius). So, if the diameter is 2 cm, then the circumference would be the product of (2) times (3.1416) times (1), or 6.2832 cm. Circumference is equal to diameter times Pi. c = Pi * d diameter times pi


How do you get circumference when you are given radius?

Circumference is equal to pi x diameter Diameter is equal to 2 times the radius Circumference would be 2 x pi x radius


Why is the circumference of a circle diameter times pi or 2 radius times pi?

What is the circumference if the Diameter equals 3 meters?

Circumference is equal to 2 times pi times the radius. The radius is half the diameter, so pi times the diameter is also the circumference. In this case, the diameter is 3 meters so 3 times pi equals 9.42 So the circumference is about 9.42 meters.


What does circumference divided by radius equal?

2 pi


How do you use pi to determine circumference?

Circumference = pi times the diameter, or pi times 2 times radius. Area = pi times (radius squared)


How do you get a circumference?

Using a compass and the circumference is measured by 2 times pi times radius or diameter times pi.


What's is the circumference of the circle if the radius is 10 in?

The circumference of a circle is equal to 2 times pi times the radius of the circle. Therefore, if the radius of the circle is 10 inches, the circumference would be 2 times pi times 10 inches, or 20 pi inches. Pi is a mathematical constant with a value of approximately 3.14, so the circumference of the circle would be approximately 62.8 inches.
