He found areas and volumes of spheres, cylinders and plain shapes. He showed that the volume of a sphere is two-thirds of the volume of the smallest cylinder that can contain the sphere. Archimedes was so proud of this concept that he requested that a cylinder enclosed a sphere, with an explanation of this concept, be engraved on his grave. Archimedes also gave a method for approximating pi. He was able to estimate the value of pi between 3 10/71 and 3 1/7. Math wasn't as sophisticated enough to find out the exact pi (3.14). Archimedes was finding square roots and he found a method based on the Greek myriad for representing numbers as large as 1 followed by 80 million billion zeros.
One of Archimedes accomplishments was his creation of the lever and pulley system. Archimedes proved his theory of the lever and pulley to the king by moving a ship, of the royal fleet, back into the ocean. Then, Archimedes moved the ship into the sea with only a few movements of his hand, which caused a lever and pulley device to move the ship. This story has become famous because Archimedes said, "Give me a place to stand on and I will move the earth. Another invention he invented was the Archimedean screw. This machine was built for raising water to highland areas in Egypt that could not receive water directly from the Nile River. This device is still used today for irrigation purposes even is some countries today.
