    By "quadrant of a circle" I assume you mean 1/4 of the area of the circle. And since there is no picture attached I am assuming that the area of the shaded area you're asking about consists of the area of the quadrant of the circle miunus the area of the triangle.

    The area of 1/4 of a circle is . The area of a triangle of base length B and height H is . So A1 minus A2 is:



    You have values for R, B and H - tell us what you get for a final answer and we'll check it for you.
