This can not be done without the stated image.
The best approximation is, of course, the exact value. A reasonable approximation is 106.
What approximation is "best" depends on the required level of accuracy.
It is 60
There is no "best" approximation. The square root is irrational and so it is a non-terminating, non-recurring decimal so adding one more digit will always make it a better approximation.
3.14 is always the best 3 digit approximation of pi.

The best shape for a parachute is a circle. This is because the circle will have a larger area that will cause more drag to slow the parachute.
