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:
Criteria for Congruence of triangles.
Step-by-step explanation:
We are given the triangles ABC and ADC. As clear from the name, the both the triangles have a common side AC.
Criterion that can be used for congruence:
1. SSS
When all the three sides of the triangle is equal to corresponding three sides of other triangle.
2. SAS
When two sides and one angle of triangle is equal to the corresponding sides and angle of other triangle.
3. ASA
When two angles and one side of triangle is equal to the corresponding angles and side of other triangle.
