This online calculator will calculate the various properties of a cylinder given 2 known values. This is a right circular cylinder where the top and bottom surfaces are parallel but it is commonly referred to as a "cylinder".

Cylinder formula:

Volume of a cylinder: V = πr2h

Lateral surface area: L = 2πrh

The top and bottom surface area: T = B = πr2

For example, When r = 2, h = 3

 

  1. To calculate V, use the following formula: πr2h. When you substitute r and h for their values, you get π22(3), which equals 37.69911 m3.
  2. To calculate L, use the following formula: 2πrh. When you substitute r and h for their values, you get 2π(2)(3), which equals 37.69911 m2.
  3. T and B are always equal. The formula to calculate them is this: πr2. When you substitute r for its value, you get π22, which equals 12.56637 m2.
  4. To calculate A, use the following formula: L + T + B. When you substitute L, T, and B and their values you get 37.69911 + 12.56637 + 12.56637, which equals 62.83185 m2.
