Just one step I didn't know about: I thought about doing Pythagoreans theorem, but I didn't know that the diagonal of the rectangle was the diameter of the circle. If I known that I think I would have gotten it. But I did learn something new. It's been about 20 years since my last math class.

Only 10% ? This is the easiest thing I've ever done, who's giving the SATs? Children?

A 5th grade problem

All of the math on the SAT is actually relatively simple. The difficulty is in the unique ways they propose problems, and the short time limit you have on sections.

Yeah, but can’t you logic that out? You can find the area of the rectangle and get it down to the last two answers, then see what the radiuses that the answers propose the circle has. Here, only J and K have -192, so it’s down to them. K proposes that the circle has a radius of 20, which is impossible since the rectangles length is longer than the radius and smaller than 20, so that just leaves J with a proposed radius of 10, which makes sense, right?

I love when people genuinely believe the SAT is meant to be a hard test. It's quite literally the bare minimum standard. What more do you expect?

I guessed correctly after looking at it for 15 seconds.

When the diagonals of a cyclic quadrilateral are diameter of a circle then it is rectangle, using this Diagonal = Diameter ² = 16² + 12² Diameter = 20 unit Area of the circle = pie(10)² unit² = 100 pie unit² Area of the rectangle = 16 × 12 = 192 unit² Required Area = (100pie - 192) unit²

That’s just a 3-4-5 triangle scaled by 4. I suspect that only 50% of students can solve it and 40% either didn’t have time or panicked.
