use algebra to find the radius, then plug the height and radius into the surface area equation
A cylinder with a surface area of 200cm2 and a height of 20cm has a volume of about 137.96cm3
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
If the surface area is 30 m2 and the height is 2 m, then the volume is 12.369 m3
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.

Make the height the subject of the fornula for the volume or surface area of the cylinder
In order to find its height, we must know either the volume or the surface area of the cylinder.
By dividing its cross-section area into its volume
Volume = Пr2h Area = 2Пr2+2Пrh (where r=radius of base, h=height of cylinder)
If the surface area is 30 m2 and the height is 2 m, then the volume is 12.369 m3
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.
* 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 answer depends on what information you are given: volume and height, or surface area and height, etc.
Surface area = 1866 square units.Volume = 6107 cubic units.
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.
Volume of a cylinder = base area times height
