If you know the cone volume and the cone radius, then
height = 3*Volume / PI * r^2
answer is D
3x° is 60° , 2x° is 40° and 4x° is 80°

How to determine the angles</h3>
Note that the sum of angles in a triangle is 180°
Solve for x in the triangle
Then,
3x° +2x° + 4x° = 180°
Add the x°
9x° = 180°
Divide both sides by 9
x° = 180÷ 9 = 20°
If x° = 20
Then 3x° = 3× 20 = 60°
2x° = 2 × 20 = 40°
4x°= 4× 20 = 80°
Therefore, 3x° is 60° , 2x° is 40° and 4x° is 80°

Answer:
A proportional relationship is a special kind of linear relationship, but while all proportional relationships are linear relationships, not all linear relationships are proportional.
Answer:
Step-by-step explanation:
The 2 figures are similar so corresponding sides are in the same ratio.
The factor is the value that you have to multiply a side in the first rectangle to get the corresponding side in the second rectangle.
12 ----> 9
So:
12 * f = 9 where f is the factor
f = 9/12 = 3/4.
