Answer 1

Answer:
`V=108in^3`

Explanation:

To find the volume od the object you must add the volume of the cylinder and the volume of the cone, as following:

`V=V_(cylinder)+V{cone}\\\\V=(\pi\ *r^2*h_(cylinder))+((\pi\ *r^2*h_(cone))/(3))`

Where is the the radius, which is:

`r=(4in)/(2)=2in`

Substituting values, you obtain:

`V=(3*(2in)^2*(8in))+((3*(2)^2*(3in))/(3))`

`V=108in^3`
