Answer 2

Answer:

Volume of Cone = 1/3*$\pi$r²h

393 = 1/3 * $\pi$ * 5 * 5 *h

= $\frac{393}{\frac{1}{3} }$ = 25 * $\pi$ * h

= 393 * 3 = 25 * $\pi$ * h

= 1179 = 25 * $\pi$ * h

= $\frac{1179}{25}$ = $\pi$ * h

= 47.16 = 3.14 * h

= $\frac{47.16}{3.14}$ = h

So,

Value of H = 15.09

Means Approximately 15 feet
