6.) A completely full spherical hot air balloon with a radius of 9 meters is being deflated at a rate of 22 cubic meters per minute. How much time must elapse for the balloon to be completely deflated? Use the volume formula and 3.14 for π . Find the volume of the full hot air balloon.
7.) Calculate the time it takes to completely deflate the balloon using the constant rate of deflation. Set up and solve a proportion.
