\(V = \frac{4}{3}\pi {r^3}\) where r is the radius. This can be done on a calculator by \(4 \div 3 \times \pi \times {6^3}\) , using the \(\pi\) or if you don’t have a scientific calculator, use 3.14) ...

The volume of a cone is \(\frac{1}{3}\) of the volume of a cylinder with the same area. The formula for calculating the volume of a cone, where r is the radius and h is the perpendicular height is: ...

A transatlantic team of researchers explain the creation of a simulation model that can help scientists mathematically correct for any errors related to a sphere's roughness. Scientists have developed ...
