Answer 1

Answer:

20:27

Step-by-step explanation:

Ratio of radii = 2:3

Ratio of heights = 5:3

Let the radius and height of the first cylinder and the second cylinder respectively be 2x and 5x, and 3x and 3x.

Then, vol. of first cylinder = π(2x)²(5x) = 20πx³

Vol. of second cylinder = π(3x)²(3x) = 27πx³

Ratio of volumes = 20πx³/27πx³ = 20/27 = 20:27
