If the cylinder is very thin doubling this lateral surface area should be sufficient. If it is not, calculate the surface area of the Circular Cylinder (lateral + base) using the outer radius of the base circle. Then add the lateral surface area of a Circular Cylinder minus the area of the base (lateral - base) using the inner radius. VOLUME: Use the Volume formula for a Circular Cylinder. Subtract the volume calculated by using the inner radius from the volume calculated by using the outer radius. is the mass of the entire body. is the density of the body. is the outer radius of the body. All of the above results assume that the body has constant density. For none constant density see the general integral forms of Mass, Mass Moment of Inertia, and Mass Radius of Gyration.
