A cone has a volume of 3 pi and a radius of 1 what is its height

The answer should be 2

Step-by-step explanation:

16 pi    = 1/3  pi    r^2    ( 12)        Divide both sides by pi

16        = 1/3        r^2     (12)         1/3   * 12 = 4

16         = 4          r^2                     divide both sides by 4

4           =             r^2                     You should be able to take it from here !

answer: 140
