Question

Find the area of the figure to the nearest tenth.

Answer 1

Answer:

21.87 ft^2.   { if π = 3.14 }

Step-by-step explanation:

Solution is based on the concept that the figure cut from the square is a semi-circle.

Here,

     The figures describes a condition where a semi-circle is removed from the square of side-length 6 ft.

    On the basis of observation, we found the side of square is the diameter of that imaginary circle( by magnitude & unit ).

So,

    Diameter of circle = 6ft

    Radius of circle = 6 / 2 ft = 3 ft.

Therefore,

⇒ Area of the figure

⇒ Area of square of side 6ft - 1 / 2 ( area of circle of radius 3 ft )

⇒ ( 6 x 6 ft^2 ) - 1 / 2 ( π 3^2 ft^2 )

⇒ 36ft^2 - 9 / 2 π ft^2

⇒ 36ft^2 - ( 4.5 x 3.14 ) ft^2

⇒ 36 ft^2 - 14.13 ft^2

⇒ 21.81 ft^2
