Answer:

8831.25 ft^2

Step-by-step explanation:

150 = diameter

75 = radius

75^2 * 3.14

5625 * 3.14

17662.5

We want to find the area of half the circle, so we will have to halve the area of the circle

17662.5 / 2

8831.25 ft^2

Answer:

8,831.25 sq. feet

Step-by-step explanation:

Hello!

If the diameter is 150, then the radius would be 75. We can solve for the area of a semicircle by solving the area of the circle and then dividng it by 2.

Solve for the area:

  • [tex]A = \pi r^2 \div 2[/tex]
  • [tex]A = 3.14(75)^2 \div 2[/tex]
  • [tex]A = 17,662.5 \div 2[/tex]
  • [tex]8,831.25[/tex]

The area is 8,831.25 sq. feet.
