The function m(t) = 31r9 models the mass in grams of a spherical zinc ball as a function of the ball's radius in centimeters. Write the inverse model to represent the radius r in centimeters of a spherical zinc ball as a
function of the ball's mass m in grams. Then find the radius if the ball has a mass of 105 grams.
