• Area = π * r2
• Perimeter = 2 * π * r
• Perimeter of shaded part = r * a
• Area of shaded part = r2 * (a - sin(a)) / 2
Circle Inscribed in a Triangle
• s = (a + b + c) / 2
• Radius (r) = √s(s-a)(s-b)(s-c) / s
Circle Circumscribing a Triangle
• s = (a + b + c) / 2
• Radius (r) = abc / 4√s(s-a)(s-b)(s-c)
