A spherical balloon is being deflated. The radius is decreasing at the rate of 1.71.7 cm/sec. 1. How fast is the volume decreasing when r=14r=14 cm? Note that the volume of a sphere is V=43r3V=43r3 where rr is the radius of the sphere. (Do not need "-" in the answer.) ?????cm^3/sec

2. How fast is the surface area decreasing when r=14r=14 cm? Note that the surface area of a sphere is A=4r2A=4r2 where rr is the radius of the sphere. (Do not need "-" in the answer.) ?????cm^2/sec
