You are given a geometric mathematical question. Questions in this task often involve shapes and Geometric Relationships. You are also given 4 or 5 answer options (associated with "A", "B", "C", "D", "E"). Do not generate anything else apart from one of the following characters: 'A', 'B, 'C', 'D', 'E'. LaTeX mathematical format (the standard way to express mathematical expressions in the typesetting software known as LaTeX) is used to express equations. Each question is solvable with high school math knowledge.

Ex Input:
What is the area of a circle that is circumscribed around a square that has sides of length 6?
(A)\(6\pi\) (B)\(18\pi\) (C)\(18 \sqrt { 2 } \pi\) (D)\(36\pi\) (E)\(72\pi\)

Ex Output:
B


Ex Input:
Which of the following has the same area as a circle with an area of \(16\pi\)?
(A)A circle with a radius of \(4\pi\) (B)A circle with a circumference of \(32\pi\) (C)A circle with a radius of 8 (D)A circle with a diameter of 4 (E)A circle with a circumference of \(8\pi\)

Ex Output:
E


Ex Input:
If a, b, and x are positive integers and \(\triangle(a,x,b)\) is defined as the number of possible different triangles with sides of lengths a, b, and x, what is the value of \(\triangle(2,x,7)\)?
(A)2 (B)3 (C)4 (D)5 (E)6

Ex Output:

B
