\(V = \frac{4}{3}\pi {r^3}\) 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) ...

Physics and Python stuff. Most of the videos here are either adapted from class lectures or solving physics problems. I really like to use numerical calculations without all the fancy programming ...

A sphere is a perfectly round solid figure. All points on the surface of the shape are the same distance away from the centre – we call this distance the radius. The formula for the volume and surface ...
