Question

The figure along side is made up of four identical semicircles . find its area​

Answer 1

Step-by-step explanation:

5 × ( Area of Semi circles ) = Total Area

5 × ( 1/2 × π × r² )

5 × ( 1/2 × 3.14 × 9 )

70.65 cm²

Answer 2

Step-by-step explanation:

given,

radius = 3cm

we know

formula of semicircle → πr²/2

according to it,

→ 3.14 × (3)²/2

→ 3.14 × 9/2

→ 1.57 × 9

→ 14.13

therefore, area of the figure is

14.13 × 4 = 56.52 cm².

Hope this answer helps you dear!
