Volume of a cone formula v= 1/3 pi r^2 h
You are given volume = 16 pi
you are given h
16 pi = 1/3 pi r^2 ( 12) Divide both sides by pi
16 = 1/3 r^2 (12) 1/3 * 12 = 4
16 = 4 r^2 divide both sides by 4
4 = r^2 I am not going to tell you the answer, I am pretty sure you can do this by yourself here, guest^m^
