Question

Someone please help i’m like desperate

Answer 1

1130.4 m^3

Explanation:

For top cone:

radius r = 6 m

height
`h_1 = 12\:m`

For down cone:

radius r = 6 m

height
`h_2 = 18\:m`

`V_(solid) = V_(top\: cone)+V_(down\: cone) \\ \\ = (1)/(3)\pi r^(2) h_(1) + (1)/(3)\pi r^(2) h_(2) \\ \\ = (1)/(3) \pi {r}^(2) ( h_(1) + h_(2)) \\ \\ = (1)/(3) \pi {(6)}^(2) (12 + 18) \\ \\ = 12\pi(30) \\ \\ = 360(3.14) \\ \\ = 1130.4 \: {m}^(3)`
