Given that vomume of a cone is 235.5 square centimeter.

Given that height of the cone is h = 9 cm

Now we have to find the radius of the cone so we need to apply formula of volume of cone.

$Volume = (1)/(3) \pi r^2 h$

plug the given values:

$235.5 = (1)/(3) \pi r^2 *9$

$235.5 = \pi r^2 *3$

$(235.5)/(3 \pi) = r^2$

24.9873260654 = r^2

take square root of both sides.

4.99873244587=r

Hence final answer is approx 5 cm.
