Answer:
Yes, Archimedes was correct.
Step-by-step explanation:
Archimedes, the famed Greek and genius mathematician, inventor, and engineer (among other names), evaluated that the value of Pi was between 3 10/71 and 3 1/7ths.
The value of Pi that matter at this particular moment is 3.1415.
Calculate what 3 and 10/71ths is.
3 10/71= 3.1408
Calculate what 3 and 1/7ths is.
3 1/7= 3.1428
Pi does, in fact, fall between these two numbers.
