Two cylinders are of the same height. Their radii are in the ratio 1: 3. If the volume of the first cylinder is 40 cc. Find the volume of the second cylinder? Pick:  A) 360 cc  B) 60 cc  C) 300 cc  D) 36 cc  E) 39 cc

Rationale: r 1 = x r 2 = 3 x π * x 2 * h = 40 π 9 x 2 h = 40 * 9 = 360 answer : a
Answer: A
