If R is the radius of a certain circle, is the area of this circle greater than the circumference of this circle?
1. 0<R<3
2. The diameter of the circle is greater than 4
1. 0<R<3
2. The diameter of the circle is greater than 4
The question asks: is\(\pi r^2 > 2\pi r\) ?
Is\(r > 2\) ?
The first statement is NOT sufficient because r can be less as well as more than 2.
The second statement IS sufficient, because it says that r > 2.
Answer: B.
what is asked, R>2 ? or R>sqrt(2) ?
Why do you think it's\(r > \sqrt 2\) ?
Given:\( \pi r^2\)
