The volume v of an ice cream cone is given by v = 2 3 πr3 + 1 3 πr2h where r is the common radius of the spherical cap and the cone, and h is the height of the cone. use linearization to estimate the change in the volume when r changes from r = 1.5 inches to r = 1.6 inches, and h changes from h = 5 inches to h = 5.1 inches. give your answer to two decimal places.
