Answer:

2.0 inches

Step-by-step explanation:

Volume of a cone is given by

[tex]V=\frac {\pi r^{2}h}{3}[/tex]

Making h the subject of the formula, the formula then

[tex]h=\frac{3V} {\pi r^{2}}[/tex]

Substituating 301.4 in³ for V and 12 in for r then

[tex]h=\frac{3*301.4} {\pi 12^{2}}=1.9987208269957in\\h\approx 2 in[/tex]

Therefore, h is 2.0 inches
