Answer #1

Given equations : Vi = 4, and z = = 8 cose (3) */3 1 / 2 A ra r2 I o B SA Id (ss) At the point of intersection, r=rz → 4 = 8(5) Area of intersection of the two curves area of OABC 2x area of OAB {due to symmetricity Hereo, area of OAB = area of regii. Area of intersection of the required curves is, 87 A = A, + A2 = Set + ( 9 T - 413) 16* - 453
