Answer:r=20 cubic inches
Step-by-step explanation: Looking at this question critically and solving it mathematically, then we are going to say the volume of cylinder is πr^2h
V=15072 cubic inches r=? H=12cubic inches
15072cubic inches=3.14×r^2×12cubic inches
15072cubic inches=37.68 cubic incher^2
r^=400
We are going to take square of both sides, and our answer will now be
r=20 cubic inches
