please help!!!!!! im so confused
a watermelon is assumed to be spherical in shape while it is still growing. Its mass, Mkg, and radius, rcm, are related by the formula M=kr^3, where k is a constant. It is also assumed that the radius is increasing at a constant rate of 0.1 centimeters per day. On a particular day the radius is 10cm and the mass is 3.2kg. Find the value of k and the rate at which the mass is increasing on this day.
