The best estimate for 3 times pi is 9 and 1/7, which is represented as 9⅙ or 9 1/7. Therefore, the correct response is "917".
the real answer is 9 3/7
Apologies for the error. You are correct. The best estimate for 3 times pi is 9 and 3/7, which is represented as 9⅓ or 9 3/7. Therefore, the correct response is "937". Thank you for pointing that out.

Using rational approximations, the statement "π < √9" is true. This is because π is approximately 3.14, while √9 is exactly 3. Therefore, π is less than √9.
