1. x=36 tells us that the area of the triangle is slightly less than 1/10th of the total area of the circle
INSUFFICIENT

2. radius = 1

so the area of the circle is (1^2)pi or just pi

If the area of the circle is pi, it's impossible for a triangle inside the circle to have an area greater than pi.
SUFFICIENT

I believe it's the symbol for pi and not an n. That's the only thing that makes sense anyway.

Hey - how did you get the area of the triangle using the radius of the circle?

I didn't.

I used the radius of the circle to see that the area of the circle is pi and that's all the information you need. If the area of a circle is pi, and you have a shape (in this case a triangle) inside the circle, there's no way the area of the shape can be greater than the area of the circle.

The question asks us if the area of the triangle is greater than pi. The triangle would have to take up the entire circle (which is impossible for a triangle inside a circle) to just get to pi for an area.
