Question

Cylinder with radius of 1.5. it holds 123 cubic inches of wax.How tall is it. I need to also know the formula how to get it.

Answer 1

See the formula, my friend:
                    V = $\pi$r²h
                  or, 123 =$\pi$(1.5)²h
                  or, h = 123 ÷ (2.25$\pi$)
                  or, h = 17.40094044
