The volume of the first is not 2 * volume of the second. They both have the same volume.
Step-by-step explanation:
The 2 cylinders described are identical. The diameter = 2 times the radius, so the radius of the first cylinder = 1/2 * 7 = 3.5 in, which is the same as the radius of the second one. Also the heights are the same so the volumes are the same too.
