Question

two cylinders have their radii and height respectively in the ratio of 2:3 and 5:3.the ratio of their volumes is

Answer 1

Answer:20:27

Step-by-step explanation:

cylinder 1

r=2x

h=5x

volume=πr²h

             = π*2x*2x*5x

cylinder 2

r=3x

h=3x

volume=πr²h

            =π*3x*3x*3x

ratio=π*2x*2x*5x/π*3x*3x*3x

       =20x/27x

        =20/27

        =20:27

         

Answer 2

First cylinder . Radius=2 and height = 3 and in second cylinder radius= 5 and height= 3 so.

volume of first cylinder /volume of second cylinder
22/7 ×2×2×3/22/7×5×5×4 = 3/25 so in ratio answer 3:25
