Splet08. jun. 2024 · Found the area of a circle (and other curved geometric figures) in organized steps of regular polygons; How was this done to find the area of the circle? Found area of a parabolic sector by a geometric argument of \[\sum_{n=0}^\infty \dfrac{1}{4^n} = \dfrac{4}{3}\] Liu Hui (China 3rd century, A.D.) used a similar method of exhaustion re: … SpletLet x be the radii of the two congruent circles. Suppose three numbers a2, b2 and c2 form an arithmetical c a progression. If (a + b) = – 12 and (c – b) = x and has the value equal to q. b a If now the roots of the equation x2 + Bx + D = 0 are r1 and r2 where r1 + r2 = 2 and r12 r22 = q then Q.1 The value of 'x' is equal to botina 90hbs400
