The volume of a cone is 16 pi cubic inches. Its height is 12 inches. What is the radius of the cone?

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      I am not going to tell you the answer, I am pretty sure you can do this by yourself here, guest^m^
