About Archimedes Archimedes was born about 287 BC, in Syracuse, Sicily in what is now known as Italy. He was a Greek scientist. He was an inventor, an astronomer, and a mathematician. He was very famous during his life and he may be one of the most clever people who have ever lived. His father was Phidias, an astronomer, and he may have been in the family of a king of Syracuse. Syracuse was a rich Greek city, on the sea shore in Sicily. When Archimedes was about ten years old, he left Syracuse to study in Alexandria, in Egypt in the school of Euclid, who was a famous mathematician. Not much is known about the personal life of Archimedes, for example, whether he was married or if he had children. A friend of Archimedes called Heracleides wrote a biography of him but sadly, this work is lost. Archimedes died trying to defend Syracuse from the Roman`s.

Archimedes’ Principle Archimede’s Principle states that the weight of water changed by an object equals the amount of buoyancy the object gets.

Principle continued Archimedes discovered how to find the volume of a sphere, V=4/3*Pi*r3, and determined the exact value of PI,

On the next slide there will be a question on what you have just learned. Are you ready?

Lets try answering a question Remember: V=4/3*Pi*r3 The radius of a sphere is 4. What is it’s volume? a) 11 Pi b) 12 Pi c) 13 Pi d) 15Pi e) 16Pi
