solong [7]

Answer:

24 feet cubed

Step-by-step explanation:

When comparing the volume formula for a cone and the volume formula for a cylinder, a cone is 1/3 of a cylinder. Therefore, divide 72 by 3 to get the volume of a cone with the same base and height. It would not be 24 pi feet cubed because 72 feet cubed is already multiplied by the pi.

A direct variation passes through the point (-3,9) given y varies directly as x find the value of y when x is 2

frutty [35]

Answer:

Step-by-step explanation:

<u>Proportions</u>

A direct proportion is a relation between variables where their ratio is a constant value. This means that if y and x are proportional, then:

y = kx

Where k is the constant of proportionality.

Substituting x=-3 y=9:

9 = k(-3)

$k=\frac{9}{-3}=-3$

Now the relationship is:

y = -3x

For x=2

y = -3(2) = -6
