Figure shows a cylinder with equations (formulae) for circumference, circle area, surface area, and cylindrical volume. This cylinder also available as a 3D stereo anaglyph.

This calculator will work out the surface area of a cylinder and the volume of a cylinder if you enter the radius and height. Only enter numbers (e.g. enter 22 not 22 cm). If you try to enter a unit of measure (e.g. 22 metres, 4 miles, 10 cm) you will get an NAN (Not A Number) error appear in each box. When you have entered the numbers, click the GET button.
SURFACE AREA OF A CYLINDER is the area of the top and bottom plus the area of the wall. The area of the top is given by the formula for the area of a circle (π r2). So you need two of those (top + bottom). Then the area of the wall, which is the height (h) times the circumference (2π r2). So the total area = 2(π r2) + h(2π r2).
VOLUME OF A CYLINDER is the area of the top times the height. The area of the top is given by the formula for the area of a circle (π r2). So the total volume = h(π r2).
To convert between lengths (e.g. centimeters to inches) see our Length & Distance Converter. For weights and volumes (especially in recipes) see our Recipe Converter. Sphere: Calculate surface area and volume of a sphere.
