Find the area of the given shape.

Answer»

RADIUS of HALF circle=10cm

radius of FULL circle=20cm

area of full circle = πr²

22/7×20×20

22/7×400

8800/7

=1257.14cm²

area of semicircle =πr²/2

22/7×20×20/2

22/7×20×10

22/7×200

=4400/7

=628.5cm²

area of half semicircle =628.5/2

=314.25cm²

area of GIVEN figure =area of full circle - area of half semicircle

1257.14-314.25
