If you have more than one question, you need to make separate posts.

The volume of a sphere is `V=4/3pir^3` , so the volume of half a sphere is `V=2/3pir^3` .

To find the volume of the hemisphere with radius 3 inches, substitute the value into the formula and simplify

`V=2/3 pi r^3`  sub in r=3

`=2/3pi 3^3`   cancel common factor of 3

`=2pi 3^2`  simplify


The volume of the hemisphere is `V=18pi` cubic inches.
