First, let's find the radius of the semicircle C using the perimeter formula:
Perimeter = πr + 2r
60.57 = πr + 2r
60.57 = 3.14r + 2r
60.57 = 5.14r
r = 60.57 / 5.14
r ≈ 11.78 inches
Now, let's find the area of the semicircle using the formula:
Area = (1/2)πr^2
Area = (1/2) * 3.14 * (11.78)^2
Area ≈ 218.41 square inches
Therefore, the area of semicircle C is approximately 218.41 square inches.
The length around the outside of semicircle C from point A to point D to point B is 37 inches. The perimeter of semicircle C is 60.57 inches.
Use 3.14 for . Round to the nearest hundredth.
The area of semicircle C is
square inches.
