To find the area of a circle, do pi times the radius squared
5 squared is 25
since we are using 3.14 as a substitute for pi, multiply 3.14 by 25
3.14*25=78.5
Since this is a half circle and not a full one, divide 78.5 in half
78.5/2=39.25
Now for the square:
If the radius of the half circle is 5, its diameter must be 10. Since the diameter is a portion of the length, add 10 to 13
10+13 =23
Then multiply 23 and 13
23*13=299
Add 299 to 39.25
299+39.25= 338.25
The area is 338.25 square feet.
Hope I'm correct and that this helps you.
