Answer: 25pi/3 square units
=============================================================
Explanation:
If that point is the center, then we have two pizza slices that sweep out 60 degrees of a central angle.
The full circle has pi*r^2 = pi*5^2 = 25pi square units of area
We only want 60/360 = 1/6 of that for each slice, so 2*(1/6) = 1/3 of the full circle area is shown by the shaded region
(1/3)*(full circle area) = (1/3)*25pi = 25pi/3 square units is the shaded area
