Answer:
Given that,
To find the shaded area in the given figure.
Explanation:
Area of the shaded region is Area of the rectangle - Area of the semicircle
we get,
Area of the semicircle:
Diameter= 8 m
Radius= 8/2= 4 m
Area of the semicircle is,
[tex]\pi r^2=\pi(4)^2[/tex]
The approximate value of pi is 3.14
Substitute the value we get,
[tex]=(3.14)(16)[/tex][tex]=50.24[/tex]
Area of the rectangle is,
[tex]=25\times8=200[/tex]
Area of the shaded region is,
[tex]=200-50.24[/tex][tex]=149.76\text{ m}^2[/tex]
The best estimate for the area of the shaded region is 149.76 m^2.
