Step-by-step explanation:

Hey there!

By using the following formula for volume of a cylinder I got,  

1: 56.52

2: 113.04

3: 113.04

4: 113.04

Now to find SA we'll use the following formula,

1: 94.2

2: 62.8

3: 138.16

4: 131.88

Now for the ratio,

56.52:94.2 - 3:5

113.04:62.8 -  9:5

113.04:138.16 - 9:11

113.04:131.88 - 6:7

Hope this helps :)
