Answer 1

To determine whether Walter is correct in estimating that $\sqrt{13}$ is between 3.61 and 3.62, we can square both values to see if they fall below or above 13.

1. Calculate ${3.61}^2$: $${3.61}^2=12.9921$$

2. Calculate ${3.62}^2$: $${3.62}^2=13.0644$$

Now we can analyze:

• ${3.61}^2=12.9921$ which is less than 13.
• ${3.62}^2=13.0644$ which is greater than 13.

This means that $\sqrt{13}$ is indeed between 3.61 and 3.62, so Walter's estimation is correct.

The correct response would be: Yes, Walter is correct.
