Question

If the volume of the cone is 220 feet', what is the missing length?

Use 3.14 for it and round the answer to the nearest hundredth.
h=?
r=5 feet
The missing length is
feet.
Enter the answer

Answer 1

h = 4.41 feet

Explanation:

`V_(cone) = (1)/(3) \pi {r}^(2)h \\ \\ 220 = (1)/(3) * 3.14 * {5}^(2) * h \\ \\ 220 * 3 = 3.14 * 25 * h \\ \\ 660 = 78.5 * h \\ \\ h = (660)/(78.5) \\ \\ h = 8.40764331 \\ \\ h = 4.41 \: feet`
