Question

Find the area of shaded region if abcd is a rectangle with sides 8cm and 6cm and o is center of circle

Answer 1

area of rectangle = l×b

8×6

48

rectangle is inner of circle

then radius of circle is 1/2 diagonal of rectangle we find that Pythagoras theoram 10

area of circle=πr square

3.14×5×5 = 78.5

then remaining area = 78.5-48

30.5 ans

Answer 2

Answer:-- THE AREA OF RECTANGLE=LENGTH×BREADTH

= 6×8

= 48 cm^2

By Pythagoras theorem the length of diagonal is 10 cm (Diameter)

Area of circle is πR^2= 3.14×5×5

= 78.5 cm^2

Area of shaded region= 78.5-48

= 30.5 cm
