Answer:

Hello eshaa 7

Hi whats up bro the ans is 1:10

Answer 2

Answer:

Given :-

• Radius of two cylinder are in ratio 1:2 and height in ratio 2:5

To Find :-

Ratio of volume

Solution :-

As we know that

Let the volume of first cylinder be V and second cylinder's volume be V'

Let us assume the Radius be 1x and 2x and height be 2x and 5x

V/V' = π × x² × 2x/π × 2x² × 5x

V/V' = x² × 2x/2x² × 5x

V/V' = 2x²/2x² × 5x

V/V' = 1:5

Hence :-

The correct answer is Option C
