　　(B) 1 over 3

　　(C) 5 over 12

　　(D) 7 over 12

　　(E) 1 over 2　　

　　Explanation

　　4.The correct answer is C

　　Since the radius of the circle is 4, the diameter of the circle is 8. In a circle, the diameter is longer than any segment that can be placed entirely inside the circle. Therefore, segments of length 8.10 or length 14.00 could not be placed entirely within the circle, and the correct answer is 7.99.

　　以上就是这八道SAT数学选择题的全部内容，很简单。但是大家一定要记得，不要拿这些SAT数学选择题的难度和真正的SAT数学考试的难度相比，因为SAT数学考试的难度比这个要高，大家从中需要了解的是SAT数学考试的出题方式和相关词汇。
