Question
The balloon shown is in the shape of a cylinder with hemispherical ends of the same
radius as that of the cylinder. The balloon is being inflated at the rate of 261n cubic
centimeters per minute. At the instant the radius of the cylinder is 3 centimeters., the
volume of the balloon is 144n cubic centimeters and the radius of the cylinder is
increasing at the rate of 2 centimeters per minute. (The volume of a cylinder is ar²h and
4
the volume of a sphere is ar').
