A spherical balloon is being deflated. The radius is decreasing at the rate of 1.1 cm/sec. 1. How fast is the volume decreasing when 1' = 20 cm? Note that the volume of a sphere is V = gnr3 where r is the radius of the sphere. (Do not need "-" in the answer.) :cnsec SubmilAnswer Tries 0/99 2. How fast is the surface area decreasing when 1' = 20 cm? Note that the surface area of a sphere is A = 4m2 where r is the radius of the sphere. (Do not need \"-" In the answer.) :cmZ/sec
