Question

What is the radius of a hemispherewith a volume of 281,250 cm??

Answer 1

Given:

The volume of the hemisphere = 281,250

Find-:

Radius of hemisphere

Explanation-:

The volume of the hemisphere is:

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

Given volume is 281250

`\begin{gathered} V=(2)/(3)\pi r^3 \\ \\ 281250=(2)/(3)\pi r^3 \\ \\ r^3=(281250*3)/(2*\pi) \\ \\ r^3=134286.9832 \\ \\ r=51.209 \end{gathered}`

So, the radius is 51.209 cm
