If pi is the ratio of its circumference to its diameter , But it cannot be written as a fraction
then how is it a ratio ?
then how is it a ratio ?
A ratio doesn't need to be a rational number. A real number is perfectly acceptable.cragar said:If pi is the ratio of its circumference to its diameter , But it cannot be written as a fraction then how is it a ratio ?
Jimmy Snyder said:A rational number is not merely a ratio of numbers, it is a ratio of integers.

That means pi cannot be expressed as the ratio of two integers.cragar said:yes but pi is irrational
Dr Lots-o'watts said:Why does everybody use circumference/diameter and call it pi instead of using diameter/circumference and call it cake (or another Greek letter)?

Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is approximately equal to 3.14159, but it has an infinite number of digits after the decimal point.
Pi is an irrational number, meaning it cannot be expressed as a finite decimal or fraction. It is usually calculated using various mathematical formulas, such as the Leibniz formula or the Gregory-Leibniz series.
Pi is an irrational number, meaning it cannot be expressed as the quotient of two integers. This is because the decimal representation of Pi never ends or repeats, making it impossible to write it as a fraction.
While Pi cannot be written as a fraction, it is still considered a ratio because it represents the relationship between a circle's circumference and diameter. It is a constant ratio, meaning it is the same for all circles, regardless of their size.
Pi is a fundamental constant in mathematics and science, appearing in many equations and calculations. It is used to calculate the areas and volumes of circles and spheres, as well as in trigonometric functions and differential equations. It also has applications in fields such as physics, engineering, and statistics.
