We want to find how the volume, V, of a balloon changes as it's filled with air. We know that V(r)=ar', where r is the radius in inches and V(r) is in cubic inches. V (3)–V(1) The expression represents Give the letter of the correct answer below. 3-1 a. The average rate of change of the radius with respect to the volume when the radius changes from 1 inch to 3 inches. b. The average rate of change of the radius with respect to the volume when the volume changes from 1 cubic inch to 3 cubic inches. c. The average rate of change of the volume with respect to the radius when the radius changes from 1 inch to 3 inches. d. The average rate of change of the volume with respect to the radius when the volume changes from 1 cubic inch to 3 cubic inches.
