What is the value of π (pi) to two decimal places?

• A. 3.12
• B. 3.14
• C. 3.16
• D. 3.18

Answer: (B)

The value of π (pi) to two decimal places is 3.14. Pi is a mathematical constant that represents the ratio of a circle's circumference to its diameter. It is an irrational number, meaning it cannot be expressed exactly as a simple fraction, and its decimal representation is non-terminating and non-repeating. In the context of rounding to two decimal places, we observe that the third decimal place (which is 1 in this case) determines whether we round up or stay the same. Since the second decimal is 4, and the next digit (1) is less than 5, we do not round up, thus keeping the value as 3.14. This knowledge is essential in geometry, particularly when solving problems related to circles, as it allows for more precise calculations involving circumference or area when approximating pi.
