compose Posted May 19, 2015 Report Posted May 19, 2015 In the diagram above, JKL is an equilateral triangle. Point M is the midpoint of segment JL, and M is the center of a circle that passes through points J and L. The shaded regions in the diagram indicate all the regions inside the circle that are outside the triangle. What fraction of the total area of the circle is outside the triangle? 5/6 - sqrt(3)/2*pi

compose Posted May 19, 2015 Report Posted May 19, 2015 explain chey :( circle radius = 1 (say) => area of circle = pi JL is the diameter kabatti, area of the bottom part of the circle = area of the top part of the circle = pi/2 top part of circle lo the points where the lines JK and KL intersect the circle are their respective midpoints. so the area of triangle within the circle is divided into 2 smaller equilateral triangles and a sector. so aa chinna equilateral triangle angle at the center M is 60 degrees and hence the area of the sector it encompasses = 1/6 * area of circle = pi / 6 deenilo nundi smaller equilateral triangle area subtract cheyali. area of smaller equilateral triangle = 1/2 * b * h = 1/2 * 1 * sqrt(3)/2 = sqrt(3)/4 hence, area of green unoccupied sector on the left side = pi/6 - sqrt(3)/4 so area of two green unoccupied sectors combined (one on left and one on right side) = pi/3 - sqrt(3)/2 hence, the area of green area = pi/2 + pi/3 - sqrt(3)/2 = 5*pi/6 - sqrt(3)/2 hence required ratio = (5*pi/6 - sqrt(3)/2) / pi = 5/6 - sqrt(3)/2*pi
