Video Summary

The problem involves finding the percentage of a circle that lies outside a triangle given specific areas. Assuming the union of the circle and triangle is 100 units, the area of their intersection is 45 units, and the area of the triangle outside the circle is 40 units. This leaves 15 units as the area of the circle outside the triangle. To find the percentage of the circle that lies outside the triangle, divide this area (15) by the total circle area (60), which includes both the intersection and the part outside the triangle. This calculation simplifies to 25%.
