pi or π is used to find the area and circumference of a circle. You can either solve it in terms of pi or solve with pi being 3.14.
Best of Luck!
Since

, and you have a corresponding term in the given Riemann sum of

, you know the integral is being taken over an interval of length 5, so you can omit the second choice.
Next,

corresponds to

with

. The fact that

alone tells you that the interval of integration starts at 3, and since we know the interval has length 5, that leaves the first choice as the correct answer.
THE ANSWER IS THE SECOND AND THIRD CHOICE.
