Ah, the area of a circle is like a happy little secret waiting to be discovered. You just need to remember this simple formula: A = πr². That means the area (A) of a circle is equal to pi (π) times the radius (r) squared. Just imagine all the wonderful landscapes you can create with this knowledge!

The circumference of a circle is the distance arround the edge of the circle. The area of a circle is how big the inside of the circle is.

The question as it stands cannot be answered. No Englishman discovered Australia and befriended Bennelong, an Aboriginal man of the Eora tribe. Australia was discovered by the Dutch, around 80 years before the first Englishman set foot on the continent. This first Emglishman was William Dampier, who landed in Austalia's northwest in 1688, long after the first recorded Dutch landing in 1606. Dampier was not even remotely interested in communicating with the aboriginal people. Almost a century later, in 1770, James Cook became the first Englishman to sight the eastern coast of Australia, but he did not befriend any Aborigines either. It has Captain Arthur Philip, who led the First Fleet to Australia in 1788, who befriended Bennelong.
Johannes Kepler discovered that the Earth revolves/orbits the Sun in an ELLIPSE. He also discovered that the Sun is NOT at the centre of the ellipse, but at one of the foci ; (plural of focus). The other focal point being 'blind'. From this we have the definition, that as the Earth orbits the Sun , 'It sweeps equal arcs in equal times'. As the Earth orbits, it speeds up and slows down. It is moving at its fastest when passing the Sun at it nearest point ( perigee) and slowest when at its furthest point ( apogee). Have a look in Wikipedia under' Johannes Kepler.
No one really because a circle is a natural geometrical shape seen throughout nature.
