Answer:

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
