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

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

3

step-by-step explanation:

divide 13.5 by 9 to get the scale factor. it equals 1.5

2 * 1.5 = 3
