Question

The volume of a cylinder is 72 cm3. If the radius is 3 cm, what is the height of the cylinder?

Answer 1

`Solution,\\Volume(V)=72cm^(3) \\Radius(r)=3cm\\Height(h)=?\\As ,\\V=\pi r^(2) h\\72cm^(3) =\pi *(3cm)^(2) *h\\(72cm^(3) )/(9\pi cm^(2) )=h\\ h=2.5464cm`

Explanation:

Hence the height ≈ 2.5464cm
