In figure, find the area of the shaded region [Use `pi=3.14`]

Explanation

Given : length of rectangle l = 8 cm and breadth of rectangle b = 6 cm

Area of rectangle `= l xx b = 8 xx 6 = 48 cm^2`

let the center of the circle is O

in right angle `/_\ ABD `

`(BD)^2 = (AB)^2 + (AD)^2`

` :. (BD)^2 = 8^2 + 6^2 = 100`

` :. BD = 10`

`:. `radius ` r = OB = (10)/2 = 5 cm`
