A rectangle is inscribed in a semicircle of radius r, as shown in the figure, where r = {6**.
Express the area A as a function of the height h of the rectangle using the given radius r of the circle.

h x square root of 72
But I could be wrong. Geometry was a long time ago....

If you notice this notice then you will notice that this notice is not worth noticing.
The area of the rectangle is 2*h*b
Can you figure out what b is, in terms of h and r?
Pythagorean Theorem: b^2 + h^2 = r^2
