Question

If the radii of two circular cylinders are in the ratio3:4 and their heights are in the ratio 6:5. Find the ratio of their volumes.

Answer 1

Answer:

27:40

Explanation:

ratio of radii=3:4

ratio of heights=6:5

r1=3,h1=6

v1=πr^2h

=π3×3×6

=π54

r2=4,h2=5

v2=π4×4×5

=π80

ratio of volume = π54/π80

=27:40
