Answer:
Explanation:
Area of shaded region = Area of rectangle - area of semicircle
Considering the rectangle,
length = 6
width = 6/2 = 3
Area of rectangle = 6 x 3 = 18
The formula for calculating the area of a semicircle is expressed as
area of a semicircle = 1/2 x πr^2
where
r = radius
From the information given,
diameter = 6
radius = diameter/2 = 6/2
r = 3
π = 3.14
Area of semicircle = 1/2 x 3.14 x 3^2 = 14.13
Area of shaded region = 18 - 14.13
Area of shaded region = 3.87 ft^2
