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.
-
Calculate \( 3.61^2 \): \[ 3.61^2 = 12.9921 \]
-
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.
