Pi, or the the ratio between a circle's circumference to its diameter, is an irrational number known to extreme precision. It is value is approximately equal to 3.14.
Although you can get an exact value by typing 502*9 into a calculator, the result will be close to 500*10, or 5,000. The grader accepts any response within 15% of the true value, 4518, so that you can use any estimation technique that you like.
If you look at your hand, you can count that you have five fingers.

Multiple Choice also allows students to select from a variety of pre-written responses, although the format makes it easier for students to read very long response options. Optionresponse also differs slightly because students are more likely to think of an answer and then search for it rather than relying purely on recognition to answer the question.
