The volume of air in a balloon is represented by the function V (r) = four-thirds pi r cubed, where r is the radius of the balloon, in inches. The radius of the balloon increases with time, in seconds, by the function r (t) = one-fourth t squared. Write a composite function that can be used to determine the volume of the balloon after t seconds. Then, select the two true statements.
