Numerical and Graphical Analysis Consider the shaded region outside the sector of a circle of radius 10 meter: and inside a right triangle (see figure).
(a) Write the area A= of the region as a function of . Determine the domain of the function.
(b) Use a graphing utility to complete the table and graph the function over the appropriate domain.
