The volume of a right-circular cylinder of radiusr and height his V-h. Suppose the radius and height of the cylinder are changing with respect to time t dv dr (a) Find a relationship between and dt dt OV dh dt dt (b) At a certain instant of time, the radius and height of the cylinder are 14 and 8 in, and are increasing at the rate of 0.3 and 0.7 in./sec, respectively. How fast is the value of the cylinder increasing? (Round your answer to two decimal places.) Select
