Answer: 5 cm



Explanation: The formula for the volume of a cylinder is pi (3.14 here) * r^2 * 3

Thus, we have 235.5=3.14r^2*3

Dividing both sides by 3 leaves us with 78.5=3.14r^2

Dividing both sides by 3.14 gives us 25=r^2

To solve the equation, we take the sqrt of both sides and we find that r is 5 cm.
