The Radius of a Cylinder calculator computes the radius of a right circular cylinder from the height (h) and volume (V) (see diagram).
INSTRUCTIONS: Choose units and enter the following:
- (V) Volume of Cylinder
- (h) Height of Cylinder
Radius (r): The calculator returns the radius and diameter in meters. However, this can be automatically converted to many other length units (e.g. inches) via the pull-down menu.
The Math / Science
The formula for the radius of a cylinder is:
`r = sqrt(V/(π*h))`
where:
- r is the radius of the cylinder
- V is the Volume of a Cylinder
- h is the height of the cylinder
Cylinder Calculators
- Cylinder Side Area: Computes the surface area of the sides of a cylinder based on height and radius.
