Make the height the subject of the fornula for the volume or surface area of the cylinder
That will depend on its height which has not been given
The answer depends on what information you are given: volume and height, or surface area and height, etc.
By dividing its cross-section area into its volume
2(pi)(r)(h)=the area of the curved surface
Divide the surface area by the circumference of the circle, which is a product of the diameter x Pi. Essentially, an unrolled cylinder is a rectangle.
The radius of a cylinder given only the height could be anything you like.
The answer depends on what information you are given: volume and radius or diameter, or surface area and radius, etc.
You cannot. You need to know the height as well. If you know the height, the surface area, A is given by A = 2*Ï€*r2 + 2*Ï€*r*h where r is the radius and h the height.
The formula for the surface area of a cylinder is given by:2Ï�r2 + 2Ï�rhandBA + 2Ï�rh.
pi*radius2*height = volume of a cylinder height = volume divided by pi*radius2
The surface area of a (circular) cylinder is the circumference of the circle times the height If you need to add the surface of the ends then add twice the area of the end circles. Given r as the radius of the (circular) cylinder and h as the height, the area A is: (2*pi*r*h) + (2*pi*r2)*2 = A
