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

The surface area of a cylinder with radius r and height h is given by:A = 2*pi*r^2 + 2*pi*r*h
This can be rewritten as a quadratic equation in r
2*pi*r^2 + 2*pi*h*r - A = 0
One solution for this quadratic equation will be negative - reject that since a radius cannot be negative. The other is positive and is the required answer.

How do you find the radius of a cylinder with a volume of 2355?
That will depend on its height which has not been given but the volume of a cylinder is pi*radius squared*height.
What is the height of a cylinder when only given the volume and radius?
Since the formula for the volume of a cylinder is PI time the radius squared times the height we can calculate the height from the other two values. The height is the volume divide by PI times the radius squared.
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.
A cone surmounted by a cylinder surmounted by a hemisphere find its volume hemisphere 6m in height cylinder 7m in height cone 5m in height not given the radius or diameter?
The radius IS given, since height of hemisphere = radius of hemisphere!
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 volume of a cylinder of radius of 5 cm?
That depends on its height which has not been given
What is the volume of a cylinder with the radius 7 and the height 6?
Volume of Cylinder = Pi x radius2 x height Therefore for a cylinder with a radius of 7 units and a height of 6 units is given by Volume = 3.14 x 72 x 6 = 923.16 (cubic units)
What is the volume of a cylinder if the radius is 5 and the height is 7?
Volume of Cylinder = Pi x radius2 x height Therefore for a cylinder with a radius of 5 units and a height of 7 units is given by Volume = 3.14 x 52 x 7 = 549.5 (cubic units)
What is the formula in finding the radius of a cylinder?
The answer depends on what information you are given: volume and height, or surface area and height, etc.
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.
If you have an objects radius and height how do you find volume?
If you are referring to a cylinder, the volume is given by the equation: V = pi * r^2 * h where pi = 3.14159265.........., r = radius and h = height
How do you find the radius of a cylinder given only the height?
The radius of a cylinder given only the height could be anything you like.
