(Problem 4 continued) C. [6 pts] A standard graphing calculator cannot evaluate integrals with unspecified parameters like r and h. However, such a calculator can be used to check your work. One method is as follows. Suppose that we measure that a = 3 and b = 6, where a and b are the measurements defined on the previous page. Do the following. i. Calculate r and h when a = 3 and b = 6 and write them in the space below. r = h = ii. Technology can be used to evaluate 8ThVT2 - y2 dy for the values for r and h you found. Plug in Jo these values, then fill in the sentence below. The integral that I am evaluating is To evaluate this integral, I used and found that to 3 decimal places, the volume of the donut is iii. Substitute the values for r and h into the expression you found in Part B and write down this expression. Then, use technology to evaluate that expression. Note that if you simply write down the result from ii. and it is not consistent with your response to Part B, you will receive 0 points for Part C
