The volume of a cylinder is π × r² × l (r is the radius of the circle and l is the length of the cylinder). To calculate the volume we multiply these values together.

How to calculate the area and volume of circles and spheres? Area of a Circle = π r2 Area of a Sphere = 4 π r2 (r represents the radius) A circle has no volume since it is a two-dimensional figure.

The shell has a thickness of t with a density of ρ 2. The first (and simple) thing to calculate is the buoyancy force. This just depends on the volume of the whole sphere, which has a radius of R ...
