# Cylinder

## Volume of cylinder, area of cylinder

The best calculator to calculate the cylinder you’ve ever seen

### Calculator

Enter values into the yellow fields - the rest will be calculated automatically.

If you change a value in the field, all the marked ones recalculate accordingly.

For decimals you can enter either **points** or **commas**

as decimal marks (but only one decimal point in a value).

The result will be in the units that you enter into the fields.

For example: if you enter decimetres, calculation will be also in decimetres.

If a **NaN** error occurs,

you have probably entered invalid values.

### Formula

d = |
2 r | [m] | |

O = |
π d = 2 π r | [m] | |

P = |
π d²/4 = π r² | [m²] | |

Q = |
π d h = 2 π r h | [m²] | |

S = |
2 P + Q = 2 π r (r + h) | [m²] | |

V = |
π d²/4 h = π r² h | [m³] | |

**r** … radius = ½ of diameter

**d** … diameter = 2 × radius

**h** … height

**S** … base center of cylinder

**o** … axis

**π** (Pi) = 3,14 (about)
