Formula

d = sqrt(4V/(pi*h)); r = d/2; SA = 2*pi*r(r+h)
  • Cylinder Diameter calculates its result from Volume (cubic units), Height (units). It uses the formula d = sqrt(4V/(pi*h)); r = d/2; SA = 2*pi*r(r+h). Change any input to recalculate the result instantly.
  • The main inputs are Volume, Height. Enter them in the units and format shown in the calculator.
  • Keep comparable quantities in compatible units whenever the formula combines or compares them.
  • Changing any input above recalculates the result with the same calculation engine used by this page.

Example: Cylinder Diameter

Inputs
