Question

Helpppp plzzz...plz give steps

Answer 1

R=3 inches that’s the answer

Answer 2

Volume of hemisphere =

`(2)/(3) \pi \: r {}^(3)`

Given volume =

`18\pi \: cube`

`(2)/(3) * (22)/(7) \: {r}^(3) = 18 * (22)/(7)`

So pi is there on both the sides so it will be cut from both LHS and RHS

`(2)/(3) * r {}^(3) = 18`

`2 * r {}^(3 ) = 18 * 3`

`2 * r {}^(3) = 54`

`r {}^(3) = (54)/(2)`

`r {}^(3) = 27`

`r = 3`

Therefore value of r=3 inches
