Ancient civilizations grappled with this geometric challenge, employing various methods to approximate this ratio.

A Greek mathematician is credited with refining these approximations through the method of in- and circumscribed polygons.

His approach was that the ratio between the perimeter and the diameter of a circle can be estimated by comparing the circumference of the circle to the perimeters of an in- and a circumscribed polygon. The polygons can be divided into triangles. The ratio between the triangles' legs and their hypotenuses can be measured linearly.

That's where the pi/delta=3.14... denotation might originate from.

This method has several limitations. He tried to increase the accuracy by increasing the number of the sides of the polygons. This approach cannot yield an accurate result.

Despite these early advances, a precise, universally accepted value of this constant remained elusive for centuries.

With its value believed to be an infinite fraction, it seemed necessary to denote it by a sign in the equations.

It was not until the 18th century that the symbol π, popularized by the mathematicians of the time, gained widespread acceptance.

Several complex formulas were introduced by different mathematicians, aimed at more accurately estimating this ratio, based on a theoretical polygon with an infinite number of sides.

All of the comparison methods mentioned above have one thing in common. They are estimating the perimeters of polygons and do not account for the curved shape of the circle.
