　　The circle shown above has centerand a radius of length. If the area of the shaded region is, what is the value of?

　　(A)

　　(B)

　　(C)

　　(D)

　　(E)

　　The correct answer is A

　　Explanation

　　In order to find the value of, you should first determine the measure of the angle that is located at pointin the right triangle. To determine this angle, you must calculate what fraction of the circle’s area is unshaded. The radiusof the circle isand its area is, or. The area of the shaded region is, so the area of the unshaded region must be. Therefore, the fraction of the circle’s area that is unshaded is, or. A circle contains a total ofdegrees of arc, which means thatofdegrees, ordegrees, is the measure of the angle at pointin the unshaded region. Since you now know that two of the three angles in the triangle measuredegrees anddegrees and that the sum of the measures of the three angles is alwaysdegrees, the third angle must measuredegrees. Therefore,.

　　The bar graph above shows the number of people in attendance at each of the four meetings of the Maple Street Block Association that were held in 2011. Only members of the Block Association can attend the meetings, and no members joined or left the Block Association during 2011. Based on the bar graph, what is the least number of members the Maple Street Block Association could have had in 2011?

　　(A) 61

　　(B) 65

　　(C) 67

　　(D) 72

　　(E) 268

　　The correct answer is D

　　Explanation

　　The highest attendance was at the spring 2011 meeting, which had 72 people attending. Since only members can attend the meetings, these 72 people must have been members of the Maple Street Block Association; thus, there must have been at least 72 members of the Block Association. If the 65, 61 and 70 people who attended the winter, summer and autumn meetings, respectively, were all among the 72 people who attended the spring meeting, then the Block Association could have had as few as 72 members in all. Therefore, based on the bar graph, the least number of members the Maple Street Block Association could have had in 2011 is 72.
