The answer is: <span>A=<span>√265</span></span>.
You're looking for the extreme values of
subject to
. The Lagrangian is

with critical wherever the partial derivatives vanish:




Substituting the first three solutions into the last equation gives



At these points, we have


so the highest temperature the bee can experience is 28º F at the point (1, 2, -2), and the lowest is -26º F at the point (-1, -2, 2).
I believe the correct situation is C
If you use metric conversion (shown below), you will find that 9 meters = 90 cm. Tell me if you need further explanation.
