The area of the composite figure with 3 semicircles connected to 3 sides of a square is (6π+16).
A semicircle is a plane shape that is a part of a circle divided into two equal parts through its diameter.
Analysis:
Since the semicircles are connected to 3 sides of a square 4cm, the diameter of the semicircle is 4cm.
Radius of semicircle = 4/2 = 2cm
Area of a semicircle = π/2 =
/2 = 2π
For three semicircles = 3 x 2π = 6π
Area of square = =
= 16
Area of composite figure = Area of 3 semicircles + area of square
Area of composite figure = (16 + 6π)
In conclusion, the area of the composite figure is (16 + 6π).
