Question

anonymous · Answer

do you have a picture?

anonymous · Answer

it wont let me copy it

anonymous · Answer

then what are the side length and base length of the large cylinder and small cylinder?

anonymous · Answer

larger first

anonymous · Answer

big one has a radius of 18 and the side is 30, the small one has a radius of 12 and the side is 20

anonymous · Answer

so it would be 18:12 for the radius' and 30:20 for the side lengths. you need to find the common ratio for both by simplifying.

anonymous · Answer

how would i do that?

anonymous · Answer

well what is the greatest common factor of 18 and 12?

anonymous · Answer

when you have that divide it with 18 and 12 and you will have the simplest form then do the same for 30:20

anonymous · Answer

you will know you have the right answer if both ratios are the same.

anonymous · Answer

the common factor is 6 fo 18:20, 30:20 is 10

anonymous · Answer

correct. so what are the ratios?

anonymous · Answer

3:3, 3:2
