Question

Literally cant find this on anything or figure it out

Answer 1

v =
`(20\pi )/(3)`

Explanation:

If we rotated this around the x axis, we would have a cone.

The volume of a cone is

v = 1/3(area of the base x the height)

v = 1/3(
`\pi r^(2)`h)

V = 1/3(
`\pi 2^(2)`5) The radius would be 2 th length show on the x axis and the height would be 5 what we see in the y axis.

v = 1/3(
`\pi 2^(2)`5)

v = 1/3(20
`\pi`)

v =
`(20\pi )/(3)` This would be the exact answer

v = 20.9 Would be the answer rounded to the nearest tenth.
