Question

estimate 3 times pi
9 1/7
6 4/7
6 3/7
9 3/7

Answer 1

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

\[
3 \times 3.14 = 9.42
\]

Now, let's analyze the provided options to find the closest estimate:

1. \(9 \frac{1}{7} \approx 9.14\)
2. \(6 \frac{4}{7} \approx 6.57\)
3. \(6 \frac{3}{7} \approx 6.43\)
4. \(9 \frac{3}{7} \approx 9.43\)

Among these options, \(9 \frac{3}{7} \approx 9.43\) is the closest to \(9.42\).

So, the best estimate for \(3\) times \(\pi\) among the given options is:

**\(9 \frac{3}{7}\)**.
