Sphere Volume
Sphere Volume
The volume of a sphere grows with the cube of its radius — relevant to tanks, bearings and droplets.
The volume is V = 4π·r³/3. where r is the radius.
Inputs
r := 0.5 m=500 mm
Apply the sphere-volume formula.
V := 4·pi·r^3/3=0.52 m^3
Results
Doubling the radius multiplies the volume eightfold. This sets the capacity of spherical tanks and the mass of balls and droplets.
Assumptions & limitations
- Perfect sphere.
- Solid (full) volume.
- Radius from the centre.
