Question

Two cylindrical jars have their diameters in the ratio 3:1, but height 1:3. Then the ratio of their volume.​

Answer 1

Step-by-step explanation:

volume of cylinder is πr²h.

radius of first cylinder is 1.5 and

radius of second cylinder is 0.5.

and heights are given in the question,

height of first cylinder is 1

height of second cylinder is 3.

ratio of their volume is = volume of first cylinder

volume of second cylinder

ratio of their volume = π×(1.5)²×1

π×(0.5)²×3

ratio of their volume = (1.5)²

(0.5)²×3

ratio of their volume = 3

1

hence the ratio of their volume is 3:1.
