A spherical snowball is melting in such a way that its radius is decreasing at 1 cm/min.
1) Find the rate at which the diameter decreases when d = 10 cm.
2) At the time when d = 10 cm, what is the rate of decrease in its volume?
3) At the time when the volume of the sphere is 36pi r^3, what is the rate of decrease of the area of cross-section through the center of the sphere?
