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 find the volume of a cylinder with nothing but the radius?

You can't. With only the radius, there is no way to know how tall the cylinder is, and therefore no way to determine its volume. Sorry :(


How do you find the height of a cylinder if you know the radius and the volume?

Division my friend.


How do you find the height and radius of cylinder with only the volume?

The volume of a cylinder is (pi)r^2h. This means the volume is dependent on both the height and the radius of the cylinder. So, one must know Volume and either radius or height to calculate height or radius respectively.


How do you find the radius and the height for a cylinder when giving its volume?

the volume of a cylinder equals pi times the radius squared times the height. If you have the volume, you can't know the radius or the height, only their proportional value. You need more information


What is the radius of a cylinder with a volume of 980?

To be able to find the radius of the cylinder, you need to know not only its volume but also its height. The best we can do is find an expression for the radius in terms of the height of the cylinder volume of cylinder = Pi x r2 x h where r is the radius of the cylinder and h is the height of the cylinder 980 = Pi x r2 x h r = square root(980/(Pi x h))


How do you find the radius of a cylinder?

If you know the height and volume of the cylinder than you can find the radius. You also have to know the formula for volume 'V', which is pi multiplied by both the radius 'r 'squared and the height 'h', or V is equal to pi x r squared x h. The height h is equal to the volume divided by the radius squared and pi.

How o you find volume?

volume of a cube is length, by width by height. To calculate the volume of a cylinder you need to know the radius and the height and multiply.


What is the volume of a cylinder with a radius of 4 cm?

The volume of a cylinder, V, is given by the formula:V = pi*r^2*h where r is the radius and h is the height of the cylinder. It is necessary to know both the radius and the height before you can determine the volume.


How do you find the height of a cylinder if the you have the diameter and volume?

By inserting the data you know into the formula for the volume of a cylinder, and solving the resulting equation for the quantity you don't know - in this case, for the height. The formula for the volume of a cylinder is: volume = pi x radius2 x length. The radius is half the diameter.


How do you find the radius of a cylinder when height and volume are given?

The volume of a cylinder is given by the equation V=2*pi*r*h V=volume r=radius h=height Since the height and volume are given in this case, rearranging the equation will show that r= V / (2*pi*h). With that equation you can find the radius of any cylinder with known volume and height.


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

That depends on what you already know about it. Formulas are just relationships between what you do know and what you don't know. I can't tell you what formula to use until you tell me what you know. Example: If you know the volume of the cylinder and its radius, then Height = Volume / pi xradius2 If you know the area of the cylinder and its radius, then Height = Area / 2 x pi x Radius If you know the volume and area of the cylinder, then Height = Area2 / 4 x pi x Volume
