Question
**Problem 11:** Find the area of each of the following shaded parts. Assume all arcs are circular. **Diagram (a):** This is a circle with two smaller circles inside it. Each smaller circle has a radius of 1 cm, and they are tangent to each other inside the larger circle. The larger circle encloses the two smaller circles completely. **Diagram (b):** This shape consists of a semicircle on top of an isosceles triangle. The semicircle has a radius of 1 cm. The triangle has a height of 2 cm, with its base being the diameter of the semicircle (2 cm). The top side of the triangle is aligned with the diameter of the semicircle.
