An isosceles triangle is inscribed in a circle of diameter 10 cm using diameter as the base. Find the area of the circle not included in the triangle.

since it is given that the base of the triangle is the diameter of the circle
therefore the base of the iso triangle is 10cm
​​the height of the triangle will become 5cm
hence the circle not included in the triangle = ar of circle - area of triangle
53.57cm2
