Volume of a cone formula     V =   1/3 pi r^2 h

 

You are given  Volume = 16 pi

you are given   h

 

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 !   cheeky
