A semicircle with radius a is inscribed in a rectangle with its diameter along one side of the rectangle. A circle with radius b is then inscribed so it is tangent to the rectangle and the semicircle, as shown. Solve for the value of a/b.

(√2+1)/(√2-1) or 5.83

As we can see above AD=AB+BC+CD AB= b√2, BC=b, CD=a, AD=a√2 a√2=a+b+b√2 a√2-a=b+b√2 a(√2-1)=b(√2+1) a/b=(√2+1)/(√2-1)= 5.83

In triangleABC, side AB = 20, AC = 11, and BC = 13. Find the diameter of the semicircle inscribed in ABC, whose diameter lies on AB, and that is tangent to AC and BC.

In a square with a side length of 1, two quarter circles are drawn and a circle is inscribed between the quarter circles, as shown in the diagram. What is the radius of the inscribed circle?

In a semicircle, the circular segment ADB is folded along AB to make the circular segment ATB. The point T is tangent to the diameter and divides the diameter into lengths of 4 and 2. What is the length of AB?

In rectangle ABCD, a semicircle CPS is drawn as shown below. The semicircle’s diameter is shared with and extends beyond side BC, it intersects side AB at Q, and it is tangent to side AD at S. If CQ = 10, what is the area of rectangle ABCD?
