Question

Geometry
Round volume to nearest tenth

Answer 1

volume=
`912.9ft^(3)` (not sure how you want to round the answer. it could be rounded to 913 or left as 912.9)

Explanation:

volume of cone: to find the height of the cone, subtract the cylinder height from the total height (H-h= cone height)

`V=\pi r^2(h)/(3) \\V=\pi (5.6)^2((6.8)/(3) )\\V=\pi (31.36)(2.2666...)\\V=71.08057\pi \\V=223.3062`

volume of cylinder:

`V=\pi r^2h\\V=\pi (5.6)^2(7)\\V=\pi (31.36)(7)\\V=219.52\pi \\V=689.6424`

add them together:

`V=223.3062+689.6424\\V=912.9486`
