The circumference of a circle equals the diameter times pi. The diameter is two times the radius. So a circle with a radius of 6 would have a diameter of 12, and a circumference of 12pi.

Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.

Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.

3.14 x radius squared = the circumference of a circle. 3.14 is PI and the radius is half of the diameter.

the Circumference is pi times 2 times radius If you know circumference then you can find the radius. once you know the radius just multiply by 2 to find the diameter.

diameter=radius squared circumference=pi times diameter

The circumference of a circle is equal to its diameter times pi. This is also equal to two times its radius times pi.

The circumference of a circle is 2*pi*radius or pi*diameter

The circumference of a circle is 3.14 times diameter. The diameter is 2 times the radius

The circumference of a circle it Pi times the diameter. The diameter is 2 times the radius. So the diameter is 135 and Pi is 3.1416. So the circumference is 424.115 metres.

Doubling the radius will give the diameter and times this by pi will give the circumference of the circle.

Circumference of a circle is the diameter times pi or 2pi times the radius. Given the diameter, circumference = 16 times pi. So, the circumference is 16pi or 50.265

The circumference is ALL the way around the circle, while the radius is only HALF way into the middle of the circle. I'm guessing you meant "What is the relationship between the radius of a circle and its circumference?" Radius is half of the diameter of a circle, circumference is PI times diameter; therefore, the circumference is PI times two times radius.

Circumference equals the diameter times pi. The diameter is 2 times radius. Radius equals Circumference divided by pi then divided by 2.

The circumference is pi times twice the radius, and the diameter is twice the radius, so the circumference is pi times the diameter: 25.13278 feet.

The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
