A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3
The volume of the cylinder would be 200 x 10 = 2,000 cm3
Make the height the subject of the fornula for the volume or surface area of the cylinder
By dividing its cross-section area into its volume
The answer depends on what information you are given: volume and height, or surface area and height, etc.
Use the formula for the volume. Replace the data you know (radius and volume), and solve for the missing data (the height). Once you have this height, it is easy to use the formula for the surface area.

The formula for the surface area of a cylinder is 2πr² + 2πrh, where r is the radius and h is the height. The formula for the volume of a cylinder is πr²h. The surface area to volume ratio can be calculated by dividing the surface area by the volume.
In order to find its height, we must know either the volume or the surface area of the cylinder.

If the radius and height of a cylinder are both doubled, then its surface area becomes 4 times what it was originally, and its volume becomes 8 times as much.
use algebra to find the radius, then plug the height and radius into the surface area equation
* means times/multiplied by Volume of cylinder: pi*radius sq.*height Surface Area of Cylinder: (2*pi*radius sq.) + (2*pi*radius*height) Formula For Surface Area sa=(2x(3.14)r2+[2x(3.14)xr]xh Formula For Volume (3.14)r2xh
The volume of a circular cylinder varies directly with the height of the cylinder and with the square of the cylinder's radius If the height is halved and the radius is doubled then the volume will be increased.
Volume = Пr2h Area = 2Пr2+2Пrh (where r=radius of base, h=height of cylinder)
