To find the volume, multiply area×height.
The height is 10, but the area hasn't been given.
To get the area, convert the diameter of 3 to a radius by dividing by 2.
The radius is 1.5, so now find 1.5². You get 2.25.
Now, multiply 2.25 by pi (π). You get 7.068 as your area.
Finally, multiply that area by 10 (the height).
You get the volume of 70.68 cubic inches.
