O is the center of the circle. The area of the shaded region is 3 ∏.
Column A Column B
The degree measure of △AOB 120
选项
A、if the quantity in Column A is greater
B、if the quantity in Column B is greater
C、if the two quantity are equal
D、if the relationship cannot be determined from the information given
答案
C
解析
O是圆心,阴影区的面积是3∏
解:本题正确答案是(C)。该题主要考扇形的面积与圆的面积之间的关系。有些考生认为∠AOB既可以是外角以可以是内角,所以本题的正确答案应该为(D)。在这一点上这类考生应当注意的:在GRE数学中,指某角时,若无特殊指明或加上某些符号表示时,一般指内角。
