Answer:
C. 21.97 inches.
Step-by-step explanation:
The formula to calculate the volume of a cone is:
[tex]V= (\frac{1}{3}) (\pi )(r^{2} )(h)[/tex]
Now we clear the formula to get that:
[tex]H=\frac{3V}{(r^{2})(\pi ) }[/tex]
Now you just put the values we have in the formula:
[tex]H=\frac{3(23)}{(1^{2})(\pi) }[/tex]
[tex]H=\frac{69}{(1)(3.14) }[/tex]
[tex]H=21.9745 }[/tex]
Since they ask you to round it up or down to the nearest hunderth, the answer is 21.97 inches.
