Question

X and Y are the centres of 2 circles on a square as shown in the figure. What is the area of the shaded portion ? (Take pie = 3.14) 1) 25.52 cm^2 3) 71.74 cm^2 (2) 28.26 cm^2 (4) 88 cm^2 ​

Answer 1

Answer:

71.74cm^2

Step-by-step explanation:

Area of shaded region = area of square- ( area of quadrant + area of semi circle)

side of square = diameter of big circle + radius of small circle = 8 +2 = 10

area of square = 10 × 10 = 100

area of quadrant = 3.14

area of semi circle = 25.12

area of shaded region = 100 - 28.36
