In the figure given below calculate the area of the shaded region correct to two decimal places: Share with your friends Share 0 Abhishek Jha answered this Dear Student, Here is the solution of your asked query: Diagonal of the rectangle acts as the diameter of circle.And diagonal = 52+122=25+144=169=13 So the diameter of circle=13cmThen, its radius=132 cmSo, area of circle=πr2=227×132×132=132.78 cm2And area of rectangle=5×12=60 cm2So area of shaded region=area of circle-area of rectangle=132.78 cm2-60 cm2=72.78 cm2 Regards -2 View Full Answer S Ramaratnam answered this Angle subtended by a diameter to a point on the circumference is 90 degrees thus the diagonals of the rectangle are the diameters thus diameter^2 = 12^2 + 5^2 sq cm diameter^2 = 169 sq cm diameter = 13 cm radius = 13/2 cm Shaded area = area of circle - area of inner rectangle pi * (13/2)^2 - 12*5 sq cm = 3.1415* (13/2)^2 - 60 sq cm = 72.728 sq cm 2 Abhijith Jb answered this even i wanna know 1
