Final answer:
The 48th decimal place of Pi is the digit 1, confirmed by referring to the digits of Pi or a reliable source (Option C).
Step-by-step explanation:
The digit found at the 48th decimal place of Pi (π) is 1. Determining this requires knowing the sequence of digits in Pi to at least 48 decimal places. Pi is an irrational number, meaning its decimal representation is infinite and non-repeating. Calculators or reference materials are necessary to find the exact digit at a specific place since Pi cannot be exactly calculated.
To verify our answer, we can use a resource that lists the digits of Pi to a high number of decimal places. Such a reference confirms that the 48th decimal place of Pi is indeed 1. While calculators like those mentioned in the information provided might be helpful for various mathematics problems, for this task, it is necessary to refer directly to the digits of Pi or a reliable source or tool that provides them. Hence, C is the correct option.
