Each of Questions 1 to 7 presents two quantities. Quantity A and Quantity B. Compare the two quantities. You may use additional information centered above the quantities if such information is given. Choose one of the following answer choices:
A if Quantity A is greater;
B if Quantity B is greater;
C if the two quantities are equal;
D if you cannot determine the relationship based on the given information.
选项
A、
B、
C、
D、
答案
D
解析
The correct answer is D. The formula for the area of a circle is πr
2
, where r is the radius. Because the area is dependent on the square of the radius, it is not apparent what increasing the radius by 1 will do to the area. The original radius is not specified for either quantity, so the increases in areas cannot be calculated; the relationship cannot be determined from the given information.
