The volume of air in a balloon is represented by the function v(n) = nr), where r is the radius of the balloon, in inches. The radius increases with time, in seconds, by the function r(t) = 4,2. Which statements are true?

When V is composed with r, the composite function is

When Vr6 shows that the volume is 9724. When the radius is increased to 6 inches.

Step-by-step explanation:

Volume is determined by if the balloon is filled with air its volume will be increased and the composite function will represent the volume of the balloon. The radius of the balloon will rise in seconds. If t seconds are consumed to reach to a radius of 6 inches then the pie function is used to determine the volume.
