diameter = 7.32 Formula: Circumference = 2 * pi * radius 23 = 2 * (3.1416) * radius 23 = 6.2832 * radius 23/6.2832 = 6.2832/6.2632 * radius 3.66 = radius diameter = 2 * radius diameter = 2 * 3.66 diameter = 7.32

Circumference of a circle in inches = 2*radius*pi or diameter*pi Both radius and diameter must be in inches

You measure circumference by multiplying the diameter by pi. If it gives you the radius, multiply the radius by 2 to get the diameter then multiply it by pi. Here are some helpful formulas: Area: A=Pi r2 Diameter (If given radius) D= r x 2 Radius (If given diameter) R=d/2 Circumference= d x pi See the related link for a helpful website to look through if you need anything else.

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.

A circle with a radius of 4.1cm has a circumference of 25.76cm.

Okay finding circumference from knowing the radius right? The radius is equal to half the diameter and circumference is equal to pi * diameter. So double the radius and multiply it by 3.14 then you will get the circumference!

The unit for a circumference is the same as the unit for length (or radius or diameter).

Radius is 1/2 of a diameter. 2.5/2 is 1.25. Radius is necessary in finding the circumference and area of a circle.

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.

The equation for finding the circumference of a circle is diameter times pi so reverse it to circumference divided by pi which leaves the diameter. The diameter is twice as big as the radius so divide the diameter by 2 and you will find the radius.

Diameter = radius * 2 Circumference = pi * diameter.

It depends on what information you have: radius, diameter, area, etc.

Circumference is pi times diameter. Diameter is circumference divided by pi. Diameter is twice the radius. Radius is half the diameter.

When you are using mathematical formulas, it is good to know the difference. For example finding the circumference or area of a circle.

Diameter = circumference/pi Radius = circumference/2*pi

The diameter is (the circumference) divided by (pi) . The radius is 1/2 of the diameter.

circumference of a circle = 2*pi*radius or pi*diameter
