h=?
r=5 feet
The missing length is
feet.
Enter the answer

Answer 1

Answer:

h = 4.41 feet

Step-by-step explanation:

$V_{cone} = \frac{1}{3} \pi {r}^{2}h \\ \\ 220 = \frac{1}{3} \times 3.14 \times {5}^{2} \times h \\ \\ 220 \times 3 = 3.14 \times 25 \times h \\ \\ 660 = 78.5 \times h \\ \\ h = \frac{660}{78.5} \\ \\ h = 8.40764331 \\ \\ h = 4.41 \: feet$
