Solve the problem.The formula for the volume of a right circular cylinder is V = ?r2h. If the height is 19 yd, then the volume is a function of the radius, r. Write the function using function notation, where the height is 19. Determine the volume if the radius is 8 yd.
A. V(h) = 19?h 152? yd3 B. V(h) = 19?h 1216? yd3 C. V(r) = 19?r2 1216? yd3 D. V(r) = 19?r2 152? yd3
