Evaluate the integral by using the limit definition (with right endpoints and subintervals of equal length) of the definite integral. $${?}_3^{11}9x^{2}dx$$. Answer the following questions: (a) What is $$?x?$$ $$?x=$$ $${?}^4$$ (b) What is each $$x_i^{?}$$ ? $$x_i^{?}=$$ (c) Fill in the blanks for evaluating the definite integral by definition: $$\begin{array}{rl}{?}_3^{11}9x^{2}dx& =\underset{n??}{\lim }\underset{i=1}{\overset{n}{?}}\\ & =\underset{n??}{\lim }\text{ Enter an exact value (no decimals). }\\ & =\end{array}$$
