Question

What is the similarity ratio of the smaller to the larger similar cones? Enter your answer as a:b

Answer 1

the ratio will be 9:25

Answer 2

To find similarity ratio a:b

We take the sides and make a proportion

`(height \ of \ smaller \ cone)/(height \ of \ larger \ cone) = (radius \ of \ smaller \ cone)/(radius \ of \ larger \ cone)`

`(9)/(15) = (6)/(10)`

`(3)/(5) = (3)/(5)`

So the ratio a:b is 3:5
