what is the ratio for the volumes of two similar cylinders, given that the ratio
of their heights and radii is 2: 3?
o a. 27: 8
o b. 9: 4
o c. 8: 27
o d. 4: 9

Option C

The ratio for the volumes of two similar cylinders is 8 : 27

Let there are two cylinder of heights "h" and "H"

Also radius to be "r" and "R"

Where π = 3.14 , r is the radius and h is the height

Now the ratio of their heights and radii is 2:3 .i.e  

Ratio for the volumes of two cylinders

Cancelling the common terms, we get

Substituting we get,

Hence, the ratio of volume of two cylinders is 8 : 27

hello from mrbilldoesmath!

answer:

x - 3

discussion:

x^2 - 9 = (x-3) (x+3)   so

(x^2-9)/ (x + 3) = x-3

you,
