The Greek mathematician Archimedes was the first to approach the subject mathematically. He came to the conclusion that pi (the constant that was at the center of the relationship) had a value somewhere between 223/71 en 22/7. The average was 3,141851. Pretty close. Later a Chinese mathematician called Liu Hui came even closer with a better approximation.

The circumference is pi times the diameter.
Yes because: circumference/diameter = pi and circumference = pi*diameter
Circumference = diameter x pi
pi
The mathematical relationship between the circumference of a circle and its diameter is given by the formula C = π * d, where C represents the circumference, d represents the diameter, and π is a constant approximately equal to 3.14159. This formula shows that the circumference is equal to π times the diameter of the circle. This relationship is fundamental in geometry and is used to calculate the circumference of a circle when the diameter is known.
