Ratio of the heights of two similar cones is 7/9
what is the ratio of their radii? ratio of their volumes??
TIA
If they are similar, the ratio of the radaii is the same.
Now consider that the volume of a cone is 1/3 PI r^2 * h
So the volume ratio will have a (7/9)^2 * 7/9 ratio
Answer:
1 3/20
Step-by-step explanation:
23/20
Rewrite
20/20 + 3/20
1 3/20
See the attached picture. Just put the lowercase letter of the points on the line opposite the points.
7p ≤ 42
p ≤ 6
