Well this is a fairly simple answer, it will be a cylinder since it’s circles being stacked making a cylinder. The volume of a cylinder is simple V=pi(r^2)h, pi(r^2) is the area of your circle/ disc in this case. Luckily we were given that area so, 30 times pi which is 94.2 given that pi=3.14.Now just multiply is by the height which is 8 inches, so 94.2 by 8 inches which is 753.6 cubic inches, or 753.6 in^3
