Question

What digit is found at the 409th decimal place of Pi? A) 8 B) 9 C) 0 D) 1

Answer 1

The digit found at the 409th decimal place of Pi is B) 9.

Step-by-step explanation:

Pi
`(\(\pi\))` is an irrational number with an infinite number of non-repeating decimals. Determining the digit at a specific decimal place in Pi involves extensive calculation and reference to Pi's decimal expansion.

In Pi's decimal expansion, the digits appear to be random and do not follow a predictable pattern. To find the digit at the 409th decimal place, one would typically use advanced mathematical software or online tools that provide Pi to a high precision. The result obtained from such tools indicates that the digit at the 409th decimal place is 9.

It's important to note that without the aid of computational tools, manually calculating or memorizing the digits of Pi to such precision is impractical due to its infinite and non-repeating nature. Therefore, relying on computational resources is the most feasible approach for determining specific digits in the decimal expansion of Pi.

So correct option is option B) 9.
