Answer 2

hint:

(a/b)^2 = 81/361

Answer 3

you want to find a/b

Answer 4

how do I find a and b?

Answer 5

you don't need to find a and b individually, you just need to find a/b, which is the ratio you need

Answer 6

Can you help me with one more question?

Answer 7

sure

Answer 8

"If the scale factor of two similar solids is 3:14, what is the ratio of their corresponding areas? What is the ratio of their corresponding volumes?

Answer 9

if the initial ratio is a/b

then the ratio of the two surface areas is (a/b)^2

and the ratio of the two volumes is (a/b)^3
