The radii of two
Given: The radii of two cylinders are in the ratio 2:3.
Heights of the cylinders are in the ratio 5:3.
Volume of cylinder is: πr2h (here r and h are radius and height of the cylinder respectively)
Let V1 be the volume of first cylinder
∴ V1 = π(r1)2h1
Let V2 be the volume of second cylinder
∴ V2 = π(r2)2h2
∴ V1 : V2 = π(r1)2h1 : π(r2)2h2
⇒ V1 : V2 = π × (2)2 × 5 : π × (3)2 × 3
⇒ V1 : V2 = 20π : 27π = 20:27
∴ V1 : V2 = 20:27
That is the ratio of their volume is 20:27.
