A cone has volume 3π.

If the cone’s radius is 1, what is its height?

If the cone’s radius is 2, what is its height?

If the cone’s radius is 5, what is its height?

If the cone’s radius is 12, what is its height?

If the cone's radius in r, then what is the height?
Im so confused on how to start

Answer :

Answer:

r=1, h=9

r=2, h=2.25

r=5, h=0.36

r=12, h=0.0625

r=r, h=9/r²

Step-by-step explanation:

Volume of a cone = πr²h/3

3π=πr²h/3

r²h=9

when r=1?

r²h=9

1²h=9

h=9

when r=2?

r²h=9

2²h=9

4h=9

h=2.25

when r=5?

r²h=9

5²h=9

25h=9

h=0.36

when r=12?

r²h=9

12²h=9

144h=9

h=0.0625

when r=r?

r²h=9

h=9/r²

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.

Volume

Volume is the amount of space that is occupied by a three dimensional object.

The volume of a cone (V) is given by:

V = (1/3)πr²h

Where r is the radius and h is the height.

For a radius of 1:

3π = (1/3)π*(1)² * h

h = 9

For a radius of 2:

3π = (1/3)π*(2)² * h

h = 2.25

For a radius of 5:

3π = (1/3)π*(5)² * h

h = 0.36

For a radius of 12:

3π = (1/3)π*(12)² * h

h = 0.02

The height of a cone is dependent on its radius. The height for a cone radius of 1 is 9.
