A storage tank will have a circular base of radius r and a height of r. The tank can be either cylindrical or hemispherical (half a sphere). Complete parts (a) through (e) below. a. Write and simplify an expression for the ratio of the volume of the hemispherical tank to its surface area (including the base). For a sphere, Equals Four thirds pi r cubed and equals 4 pi r squared.
