Question

16. Two circular cylinders of equal heights have their radii in the
ratio of 3:4. Find the ratio of their volumes.​

Answer 1

Step-by-step explanation:

volume of cylinder 1= πR²h

volume of cylinder 2= πr²h

Ratio of their volumes = πR²h/πr²h

=π(3x)²h/π(4x)²h

=9/16

Therefore,ratio of their volume= 9:16
