three cones have a volume of 192π cm³.Cone A has a radius of 2 cm. Cone B has a radius of 3 cm. Cone C has a radius of 4 cm. find the height of each one

Answers

9514 1404 393

Answer:

  A: 144 cm

  B: 64 cm

  C: 36 cm

Step-by-step explanation:

The volume of a cone is given by ...

  V = (1/3)πr²h

Solving for h, we get ...

  3V/(πr²) = h

Filling in the given values, we get ...

  3(192π)/(πr²) = h

  576/r² = h

Then the heights of the different cones are ...

  A: r = 2, h = 576/4 = 144 . . . cm

  B: r = 3, h = 576/9 = 64 . . . cm

  C: r = 4, h = 576/16 = 36 . . . cm

Answer:

c = 15

Step-by-step explanation:

The angles are4 a linear pair and are supplementary, so the sum of their measures is 180 deg.

7c - 7 + 6c - 8 = 180

13c - 15 = 180

13c = 195

c = 15

The answer should be 15.

Explanation:
The line equates to 180, so you would put both equations (7c-7 , 6c-8) together and equal it to 180°.
So, it would come out looking like this:
7c-7+6c-8=180.

You’d add 7c and 6c to get 13c, and then subtract -8 from -7 (-7-8) to get -15.
The equation would now look like this.
13c-15= 180.

You’d add 15 to 180 to get 195. Then, you’d divide 195 by 13 to get 15, which would mean c=15.

Answer:

  1/30

Step-by-step explanation:

The zeros of the function are ...

-32 (multiplicity 2)5

So, the factorization for some leading coefficient 'a' is ...

  y = a(x +3)(x -2)²(x -5)

and the y-intercept is ...

  y = a(3)(-2)²(-5) = -60a

The graph shows the y-intercept is -2, so we must have ...

  -2 = -60a

  1/30 = a

The leading coefficient is 1/30.
