50. Cans A and B are both right circular cylinders. The radius of the base of Can A is 4 times the radius of the base of Can B, and the height of Can A is 5 times the height of Can B. The volume of Can A is how many times the volume of Can B?

(Note: Vcylinder = πr2h)

Answer and Explanation

Your Answer is

Correct Answer is J

Explanation

From the question, it can be seen that the volume formula of a cylinder is V=πr2 h. It is known that the radius of the bottom surface of cylinder A is 4 times the radius of the bottom surface of cylinder B, and the height is 5 times the height of cylinder B, then the volume is 42×5 = 80 times, so choose J
