Answer 2

Answer:

1:4

Step-by-step explanation:

Let the radius be r and the height be h.

Volume of the original cylinder V₁ = πr²h

(i) Radius is halved and height is same:

Radius of the new cylinder = (1/2) * r = r/2

Height of the cylinder = h.

∴ Volume of the new cylinder V₂ = π(r/2)² * h

                                                       = πr²h/4.

Ratio of the volume of cylinder:

= V₂/V₁

= πr²h/4πr²h

= 1/4

= 1:4.

Hope it helps!
