What is the formula for the diameter or a circle?

If you are given the radius of the circle, you can use the formula: diameter = 2*radius If you are given the circumference of the circle, you can use the formula: diameter = circumference/pi


If you are given a radius and asked to find the diameter what do you do?

You just multiply the given radius by 2. That is diameter is just double of the radius. This is universal formula.


What is the formula for the circumference of a circle given a radius?

Circumfrence=diameter X 3.14 (diameter=2 X radius)


What is the formula to find circumference when you are given the radius?

To find the circumference of a circle the formula is: 2*pi*radius or diameter*pi


What is the formula for calculating radius?

If it is just the radius, it is half of the diameter. If you are given the circumference, divide the given measure value by 3.14. Then, divide the result by 2 to get the radius! Have fun! If you need any help with other math formula's just post another answer. I'll write full, complete, and correct answers that I'm sure about. David (venom751998)


What is the formula for finding diameter when given the area?

Assuming you mean a circle, use the formula for the area of a circle, which is usually expressed in terms of the radius, and solve for the radius. Then you can multiply that by two to get the diameter, since the diameter is twice the radius.


What is the formula to find a circumference if the radius is 3 and the diameter is 6?

The circumference of a circle is given by the formula C = 2πr where r is the radius. But, as the diameter is 2 x radius then the formula can be written C = πd where d is the diameter. In this example the circumference = 2π3 = 6π = 18.85 units.


What is the formula for the area of the circle given the diameter?

in place of r (radius) write d/2 where d is diameter


Formula to find circumferance given diameter?

Radius is half of the diameter, so you can easily come up with a formula: L = 0.25 * pi * d2


What is the formula in finding the height of a cylinder?

The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.


How do you find the radius if the diameter is given?

the radius is half the diameter


How do you find radius when given a diameter?
