The triangle in a diagram is equilateral. The smaller circle is tangent to all three sides of the triangle. The larger circle passes through all three vertices of the triangle. What is the ratio of the area of the smaller circle to the area of the larger circle?
The diagram below shows a triangle and two arcs of circles. The triangle ABC is a right-angled isosceles triangle, with AB = AC = 2. The point P is the midpoint of [BC]. The arc BDC is part of a circle with centre A. The arc BEC is part of a circle with centre P. A B C D E P 2 2 (a) Calculate the area of the segment BDCP. [3]
Arc Length = (2 IT r) 360 Example: Find the arc length AB 120 circumference of entire circle percentage (portion) of the entire circle Since the radius is 5, the circumference of the whole circle is Arc AB is 120 360 Therefore, AB 3 of the circumference of 10 10.47 units (converting radians/degrees) (radians) = 360
