Answer 2

1. 3:5
2. 9:25
3. 3:5
4. 3:5
5. 27:125
6. 3:5

Explanation:

Here it is given that the scale factor of two cylinders is 3:5 . And we need to find out the ratios of circumference , surface area , height , diameter , volume and radii of the cylinders .

So let us assume that ,

• Radius of first cylinder be 3x and that of second be 5x .
• Height of first cylinder be 3y and that of second be 5y .

Formulas to be used :-

Circumference :- The base of cylinder is circle . So ,

`\longrightarrow C = 2\pi r`

Surface Area :- The curved surface area is ,

`\longrightarrow S.A. = 2\pi rh`

Diameter :-

`\longrightarrow d = 2r`

Volume :-

`\longrightarrow Volume = \pi r^2h`

Now refer to the attachment for answer .
