Answer:
Using 3.14 as pi, the answer would be 56.52, and using just pi (as in the input on a calculator) would be 56.54867.
Step-by-step explanation:
The equation for circumference of a circle is C = πd, C representing the circumference and d representing the diameter. Since the equation shows the radius, the equation can also be C = 2πr, since the radius is half of the diameter. Multiply nine by two to get eighteen. 18 times 3.14 = 56.52.
The first expression, 12C3, is the right answer. There is no limitation saying that the team must be made up of one student from each year level. Furthermore, no distinction has been made among the three players (no assignments of Boards 1, 2, or 3), as the question just asks how many different groups. Since order does not matter, this is a combination. (If order mattered, this would be a permutation).
