The volume of a cylindrical tank is given by the formula V=pieh r^2 where h is the height of the cylinder and r is its radius. Find the volume to the nearest tenth of a cubic foot, radius is 3 feet and height is 5 feet.

so r is two times the feet, 3x2x5=30 cu,ft, this I think is wrong or I'm missing something. thanks for helping and checking.
