### What dimensions do you need for a cylinder to have the same volume as a sphere with a radius of 7?

Volume sphere = 4/3 πr³ = 4/3 π 7³ = 1372π/3
Volume cylinder = πr²h = 1372π/3
→ r²h = 1372/3
So as long as the radius of the cylinder is related to its
height by:
radius = √(1372 / (3×height))
or
height = 1372 / (3×radius²)
You can have a cylinder of almost any size you want.
Example sizes:
radius 1, height 1372/3
radius 7, height 28/3
height 7, radius 14/√3
height 28/3, radius 7
height 49, radius √(28/3)
