Understanding Pi: Why is it a Constant Ratio in Geometry?

Explore why pi is a consistent ratio of circumference to diameter in circles and its significance in mathematics.

0 views

Pi is a ratio because it represents the relationship between the circumference and diameter of any circle. Specifically, pi (π) is the constant ratio C/D, where C is the circumference and D is the diameter. Regardless of the circle's size, this ratio remains the same (approximately 3.14159), making pi a fundamental constant in geometry and mathematics.
