Answer 2

Answer:

See below

Step-by-step explanation:

7)  a rectangle   12 x 8 = 96

     plus semi-circle   1/2  pi r^2 = 1/2 pi 4^2 = 25.132

          total = 121.132 m^2

8)  Circle area = pi r^2

       large circle   pi * 2^2  = 4pi

            MINUS the smaller one   pi 1.5^2 = 2.25 pi

                    total = 1.75 pi = 5.498 in^2

9) Square area = 10 x 10 = 100

      minus circle  pi r^2 = 25pi      total = 21.46  ft^2
