A spherical balloon is being deflated. The radius is decreasing at the rate of 1.4 cm/sec. 1. How fast is the volume decreasing when r = 13 cm? Note that the volume of a sphere is V = r³ where r is the radius of the sphere. (Do not need "-' in the answer.) cm³ /sec Tries 0/99 2. How fast is the surface area decreasing when r = 13 cm? Note that the surface area of a sphere is A = 4r² where r is the radius of the sphere. (Do not need "-" in the answer.) cm? /sec Tries 0/99
