The radius of the two cylender are in the ratio3:6 and the ratio of he

1.	The radius of the two cylender are in the ratio3:6 and the ratio of height is 2: 9 find theratio of their volume
Answer» ANSWER: plz mark me BRAINLIEST Step-by-step explanation: Since the radii are in the ratio 2:3 they can be taken as 2R and 3r units respectively. Since it is given that both cylinders have same height, let it be h units Volume of a CYLINDER is πr^2 h Ratio of volumes = π (2x)^2h/π (3x)^2 h = π 4x^2 h/π 9h^2 h = 4:9 So ratio of volumes 4:9 Conclusion: Ratio of volumes of cylinders is as the ratio of square of the radii if the height remains the same.

plz mark me BRAINLIEST

Step-by-step explanation:

Since the radii are in the ratio 2:3 they can be taken as 2R and 3r units respectively.

Since it is given that both cylinders have same height, let it be h units

Volume of a CYLINDER is πr^2 h

Ratio of volumes = π (2x)^2h/π (3x)^2 h

= π 4x^2 h/π 9h^2 h = 4:9

So ratio of volumes 4:9

Conclusion: Ratio of volumes of cylinders is as the ratio of square of the radii if the height remains the same.
