Question

The area of the following figure in square centimetres

Answer 1

hiii!!!

here's ur answer...

area of semi circle (radius=7cm) = 1/2πr²

= 1/2×22/7×7×7

= 11×7

= 77cm²

area of both semi circle (radius=7/2cm) means area of one circle.

therefore total area of both semi circles = πr²

= 22/7×7/2×7/2

= 11×7/2

= 77/2

= 38.5cm²

hence total area of the figure = 77+38.5

= 115.5cm²

therefore correct option is a) 115.5cm²

hope this helps..!
