<p>I don't know why, but ever since I started studying for the SAT math, I've been afraid of every problem that involved "shaded regions". I just hate them, and don't know how to solve the problems that involve shaded regions. I also hate problems that have the "inscribed in a circle" thing. I never learned about these stuff. How can I get better at these type of problems? Where can I review? I swear to good, I never learned how to do problems that involve "shaded regions" and "inscribed a circle"</p>
<p>Those types of questions are all about geometry. And on the SAT, you really only have to work with rectangles/square, triangles and circles. Those questions you’re afraid of are just combinations of those shapes. Just don’t immediately think you can’t do them, because that’s the kiss of death. You won’t be able to do them if you think you can’t!</p>
<p>Both the shaded area and inscribed circle questions generally start with finding the areas of those shapes. Sometimes it helps to write the information they give you on the diagram. Since you don’t give a specific problem you’re stumped by, let’s just take a circle inscribed in a square. Just look at it. By definition the diameter of the circle is going to be the same length as the side of the square. Just knowing that gives you lots of other information. If you know that length you now know the radius of the circle which leads to the area or the circumference. It also gives you the perimeter and area of the square. And to take it a step further, if the areas between the circle and the square are shaded, you can find that area by just subtracting the area of the circle from the area of the square. This may be a bit simplistic, but it give you an idea of the process. Work with what you know, then put the parts together.</p>
<p>No fear!</p>
