Use geometry (not Riemann sums) to evaluate the definite integral. Sketch the graph of the integrand, show the region in question, and interpret your result. ${?}_0^{11}\sqrt{121?x^2}dx$ Choose the correct graph below. A. B. B. c. D. The value of the definite integral ${?}_0^{11}\sqrt{121?x^2}dx$ as determined by the area under the graph of the integrand is (Simplify your answer. Type an exact answer, using $?$ as needed. Use integers or fractions for any numbers in the expression.)
