Answer 1

The volume of the resulting solid is
`28\pi`

Explanation:

The generated solid after the rotation would be a cilynder with 2 as radius of the base and 7 as its height. Also, the volume of a cilynder follows:

`V=\pi *r^2*h`

where r is the radius of the base and h is the height. Then, we'd have:

`V=\pi (2)^2(7)=28\pi`
