Question

Can you please help me out with a question

Answer 1

The volume of a hemisphere is

`V=(2)/(3)\pi(r)^3`

Where V = 56.549 cubic units.

`\begin{gathered} 56.549=(2)/(3)\cdot3.14\cdot(r)^3 \\ 56.549\cdot(3)/(2\cdot3.14)=r^3 \\ r\approx\sqrt[33]{27} \\ r\approx3 \end{gathered}`

Hence, the radius is 3 units long.
