Archimedes discovered how to work out the area of the circle, and he also discovered pi.
The ratio of the circumference of a circle to its radius.
Archimedes created the formula for measuring the circumference of a circle he used many-sided polygons, both inside and out to approximate it.
the amount of space inside a circle
If you measure the middle of the circle and then times it by 3
He tried to and his method was soundly based. His estimate, of approx 3.1485, was too large by a little over 0.2%.
In speaking about the ancient Greek mathematician, Archimedes of Syracuse discovered the ratio of the radius of a circle to its circumference. This, plus the formulas for the surface and volume of a cylinder and a square. He also designed the defenses against Roman legions and warships.

Archimedes made a number of significant contributions to mathematics. These include studies on the sphere and cylinder, the measurement of the circle, and the circumference / diameter ratio.

Archimedes of Syracuse, probably known best for his invention, the Archimedes screw, provided an approximation of the ratio of a circle's diameter to it's circumference around 300 B.C. He did this by approximating a circle as a polygon with an infinite number of sides. When the polygon had 96 sides each, he calculated the lengths of their sides and showed that the value of pi lay between 31⁄7 (approximately 3.1429) and 310⁄71 (approximately 3.1408), consistent with its actual value of approximately 3.1416. The greek letter Pi was given to Archimedes' ratio by William Jones in 1706. Ludolph van Ceulen had provided an approximation to this number accurate to 30 digits around the year 1600.
3.14 or 22/7 and the definition is A transcendental number, approximately 3.14159, represented by the symbol π, that expresses the ratio of the circumference to the diameter of a circle and appears as a constant in many mathematical expressions. The first theoretical calculation of a value of pi was that of Archimedes of Syracuse (287-212 BCE), one of the most brilliant mathematicians of the ancient world. Archimedes worked out that 223/71 < pi < 22/7.
