1.	OAB is a quadrant of a circle with OA (= OB) as its radius of length 4 cm. OA and OB are also diameters of two semi-circles as shown in the diagram below which is not drawn to scale. Shaded areas x and y are as shown in the diagram. What is the value of x y ?
Answer» OAB is a quadrant of a circle with OA (= OB) as its radius of length 4 cm. OA and OB are also diameters of two semi-circles. Shaded areas x and y are as shown in the diagram. To Find : What is the value of x/y Solution:area of OAB = (1/4)π(4)² = 4π cm²Area of one small semicircle = (1/2)π(2)² = 2π cm²Area of 2 smaller semicircles = 2 * 2π = 4π cm²Area of 2 smaller semicircles - x + y = area of OAB=> 4π - x + y = 4π=> x = y=> x/y = 1 Learn More: plot three poinys A,B,C which have same ABSCISSA 4 but lie in 1ST and brainly.in/question/10685225 the point whose abscissa is equal to its ORDINATE which is equidistant ... brainly.in/question/10112102
