A: 22:23
B: 16:19
C: 25:29
D: 20:27
Best Answer
Explanation:
The ratio of radii of two cylinders is 2:3.
The ratio of their heights is 5:3.
It is required to find the ratio of their volumes.
Let the radius of 1st and 2nd cylinders be 2r and 3r respectively.
Let the height of 1st and 2nd cylinders be 5h and 3h respectively.
Therefore,
Final answer:
Option D is correct, that is,
The ratio of their volumes is 20:27.
