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.

You need to know it's density to find the volume, then 4/3 pi r^3 to get radius, then double radius is diameter.

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

You know that for a cylinder: V = (pi)r2h where V is the volume, r is the radius, and h is the height. You also know that diameter = 2r. So, plug in your known values for volume, height, and pi in the first equation to solve for r. Then, multiply r by 2 to find the diameter.

If you do not have the area, what do you have? The radius is half the diamiter The radius is PieR2 Worked backwards if you know the circumfrence.

Division my friend.

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 :(

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.

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

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.

If you know the radius, use the formula: volume = (4/3) x pi x radius3.If you know the radius, use the formula: volume = (4/3) x pi x radius3.If you know the radius, use the formula: volume = (4/3) x pi x radius3.If you know the radius, use the formula: volume = (4/3) x pi x radius3.

You already know the radius.

You use algebra. You know that the volume of a cylinder is: Volume = (pi)(radius2)(height) If you divide each side by (pi) and (radius), you get: Volume/[(pi)(radius2)] = height

Radius of cone = 19/2 = 9.5 mm Volume = (1/3) PI r^2 h, where r is the radius and h is the height, We need to know the height of the cone to find its volume.
