Pi (π) is approximately 3.14159. However, it's crucial to understand that pi is an irrational number, meaning its decimal representation goes on infinitely without repeating.
Here's a more detailed breakdown:
-
Approximate Value: For most practical calculations, 3.14 or 3.14159 are sufficient approximations.
-
Irrational Number: Pi cannot be expressed as a simple fraction (a/b, where a and b are integers). This means its decimal expansion never terminates or repeats.
-
Decimal Representation: Here are the first few decimal places of pi:
3.141592653589793238...
-
Significance: Pi represents the ratio of a circle's circumference to its diameter. It's a fundamental constant in mathematics and physics.
In summary, while we often use approximations like 3.14, the true value of pi extends infinitely in its decimal form without any repeating pattern.
