Question

Which is the best estimate for 3 times pi?(1 point) Responses 637 6 Start Fraction 3 over 7 End Fraction 937 9 Start Fraction 3 over 7 End Fraction 647 6 Start Fraction 4 over 7 End Fraction 917

Answer 1

To find the best estimate for \( 3 \times \pi \), we can use the approximate value of \( \pi \approx 3.14 \).

Calculating \( 3 \times \pi \):

\[
3 \times \pi \approx 3 \times 3.14 \approx 9.42
\]

Now, let's analyze the options given:

- 637
- 6 Start Fraction 3 over 7 End Fraction (which is approximately \( 6.43 \))
- 937
- 9 Start Fraction 3 over 7 End Fraction (which is approximately \( 9.43 \))
- 647
- 6 Start Fraction 4 over 7 End Fraction (which is approximately \( 6.57 \))
- 917

Among these options, \( 9 \) Start Fraction \( 3 \) over \( 7 \) is the closest to \( 9.42 \).

Thus, the best estimate for \( 3 \times \pi \) is:

**9 Start Fraction 3 over 7 End Fraction**.
