The cone in the figure below has a volume of 72π cubic centimeters and a height of 6
AleksAgata [21]

Answer:

6 cm

Step-by-step explanation:

The volume of a cone = (1/3) πr²h

72π = (1/3) π r² 6

72 = (1/3) r² 6

Divide both sides by 6

12 = (1/3) r²

Multiply both sides by 3

36 = r²

So r (radius) = 6 cm

Answer: x=185

To checkt:
0.75(185)-18.5=138.75-18.5=120.25

PLS HELP. BRAINLIEST/5 STARS TO CORRECT ANSWER
fenix001 [56]

Where p is the distance the focus is above the vertex, the equation of a parabola with vertex (h, k) can be written as

... y = 1/(4p)·(x -h)² +k


The vertex is halfway between the focus and directrix. The focus of your parabola is on the y-axis at y=6, and the directrix of your parabola is at y=-6, so the vertex of your parabola is on the y-axis at y=0. That is, the vertex is

... (h, k) = (0, 0).


The distance p from the focus at y=6 to the vertex at y=0 is 6 units, so

... p = 6.


Filling these values into the equation gives

... y = 1/(4·6)·(x -0)² +0

... y = (1/24)x²
