Question

Am I correct? What is the height of the bigger cone?

10 ft

12 ft

5 ft

6 ft

Is it 6 ft?

Answer 1

How did you get 6 ft?

Answer 2

Are the cones similar? If they are it can't possibly be 6.

Answer 3

They are similar.

Answer 4

the assumption I'd gather is that they indeed are similar

Answer 5

6/8=9/x find x

Answer 6

Wait, what would x be? Or would I have to use that equation

Answer 7

12

Answer 8

Step 1: Find the ratio of corresponding measurements in pairs of similar shapes.
Step 2: Use that ratio to find the unknown lengths.
The ratio between the base and height of the small cone should equal the ratio between the height and base of the larger cone because of they are similar. The unknown value, the height of the larger cone, was represented with an x so that I could make an equation. Have you ever worked with similar triangles? This is the same thing basically.
