$which number is closest to \$\\sqrt{22}\$ ? 3.9 5.1 4.6 4.1$

which number is closest to \$\sqrt{22}\$ ? 3.9 5.1 4.6 4.1

$3.9^2 = 15.21$, $5.1^2 = 26.01$, $4.6^2 = 21.16$, $4.1^2 = 16.81$

$|22 - 15.21| = 6.79$, $|22 - 26.01| = 4.01$, $|22 - 21.16| = 0.84$, $|22 - 16.81| = 5.19$

The smallest difference is 0.84, corresponding to 4.6.
