Question

These two right cylinders have the same height, 25 centimeters. The radius of the smaller cylinder is 5 centimeters and the radius of the larger cylinder is 3 times greater than that of the smaller cylinder. What is the ratio of the volume of the larger cylinder to the volume of the smaller cylinder? A. 6:1 B. 12:1 C. 9:1 D. 25:1

Answer 2

9514 1404 393

Answer:

C. 9:1

Step-by-step explanation:

The volume is proportional to the square of the radius. When the ratio of radii is 3 : 1, the ratio of volumes is 3^2 : 1^2 = 9 : 1.
