Question

Pre algebra help me please​

Answer 1

The area is 338.25 square feet

Answer 2

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.
