How do you find the diameter if you only have the radius?
Multipy by 2 for the diameter
How do you find the volume of a cylinder if you only have the height?
The simple answer is - you can't ! You need the addition of either the diameter or radius in order to calculate the volume.
How do you find the volume of a cylinder if you do not know the radius?
So you know this is the equation you are suppose to be using. If the equation gives you the diameter of the cylinder then divide that number in half and plug the number you got into the equation. This is because the radius is half of the diameter. Otherwise, the only way to find the volume is if you have the area of the base. Then multiply that area by the height.
How do you determine the radius if you only have the diameter?
to determine the radius if you only have the diameter, you divided the diameter by 2. then there you have it ! you have the radius !
How do you find the height and radius of a cylinder with only the area of the base?
With the area of the base known, you can back figure to the radius. But unless you know the cylinder's volume, or are told that it's height is equal to the radius or diameter or circumference of the base, there's no way to find the height short of measuring it. To find the radius, you take the area of the base and divide it by pi. The resulting dividend is r2. Find the square root of the dividend, and you have the radius.

How do you find the radius of a cone knowing only the diameter?
The radius is half the diameter, so just divide the diameter by 2.
How do you find the circumference of a cylinder?
The circumference of a cirlce can be found if you know either the diameter (the longest distance from on side on the circle to another) or th radius (half of the diameter). If you know the radius, multiply it by 2 to find the diameter. The cricumference = pi x D This means you times the diameter by pi (3.1415926535...)

The radius of a cylinder given only the height could be anything you like.

What relationship between the diameter and the radius of a cylinder?
AnswerThe diameter of a cylinder is the straight line that passes all the way through the center of the circle. The radius is half of the diameter, and only goes to the center point of the circle.d = 2r ; r = 1/2 d

Do you have to find the radius for diameter?
Not necessarily. The diameter is only twice the radius, so that's an easy way to find the diameter. However, if you have the circumference, you can divide by pi to get the diameter, or just measure across the circle.
How do you find the circumference of an object if you only have the diameter and the radius?
2 x pi x radius
