Formula

Vcylinder=πr2hV_{\text{cylinder}} = \pi r^2 h

Area of the circular base times the height.

Vcone=13πr2h,Vsphere=43πr3V_{\text{cone}} = \tfrac{1}{3}\pi r^2 h,\quad V_{\text{sphere}} = \tfrac{4}{3}\pi r^3

A cone holds one third of the matching cylinder.

Come usare questa calcolatrice

  1. Choose the solid; the inputs change to match it.
  2. Enter the measurements in one unit; the answer is in that unit cubed.

Esempio svolto

Cylinder with radius 3 and height 5

V = π × 3² × 5 = 45π ≈ 141.371669 cubic units.

Domande frequenti

Why is the answer written with π?

It is the exact value. The rounded decimal is shown underneath.

Radius or diameter?

Use the radius — half the diameter.
