A right come has a volume of 24pie cubic meters and a radius of 3 meters find the height of the cone

JulijaS [17]

Hello!

The equation for find the h when given volume and radius is

$h = 3 \frac{V}{ \pi r^{2} }$

h is height
v is volume
r is radius

Put in the values you know

$3 \frac{24 \pi }{ \pi 3^{2} }$

Since there is pi on the top and bottom we can get rid of it

multiply the 3 by the top number

$\frac{72}{9}$

the answer is 8m

Hope this helps!

Which is not a proportianal relationship A y=x, B x-y=2, C=y=2x and D x +2y=0

noname [10]

Answer:

Choice B

Step-by-step explanation:

Choice B is not a proportional relationship because it is not in the form of Y = KX.

First, you must convert the equation, X - Y = 2 to Y = MX + B by subtracting X to the right side to get -Y = -X +2. Then divide each side by -1 to get a positive Y value. Then you are left with Y = X - 2, which is not in the form of Y=KX.

Solve : |1/5x - 7 | =4

Mnenie [13.5K]

Answer:

x = 55 or x = 15

Step-by-step explanation:

Solve Absolute Value.

We know that either 1/5x - 7 = 4 or 1/5x - 7 = -4.

1/5x - 7 = 4

1/5x - 7 + 7 = 4 + 7

1/5x = 11

1/5x (5) = 11 (5)

x = 55 (one possibility)

1/5x - 7 = -4

1/5x - 7 + 7 = -4 + 7

1/5x = 3

1/5x (5) = 3 (5)

x = 15 (second possibility)
