Question

Find the area of the above region​

Answer 1

Answer:

area = AREA OF SEMI CIRCLE = πr²/2

r=14+7=21 cm

22/7×21×21/2

22×3×21/2

22×63/2

1386/2

693 cm²

area of first smaller semicircle with r = 7/2

πr²/2 = 22/7×7/2×7/2/2

11×7/2/2

77/2/2

38.5/2

19.25 cm²

area of second semicircle with r=14/2

πr²/2 = 22/7×14/2×14/2/2

22/7×7×7/2

22/2×7

11×7

77cm²

total area = Sum of all the semicircles

therefore, 693+19.25+77= 789.25 cm²
