The circumference of a circle is 25.12 feet. What is the circle's area?

Use 3.14 for .

Answer: 50.24

Step-by-step explanation:

To find the circle's area, you need to first identify what the radius is by using the circumference formula (C = 2πr). Remember that the circumference is π times the diameter of the circle or 2 times the radius.

25.12 = 2 (3.14) (r).

25.12 = 6.28r Multiply 2 and 3.14 together

4 = r Divide both sides by 6.28

Now that you know the radius, you can now determine the circle's area. This can be found by using the area formula which is A = πr². You would need to change π to 3.14, so the formula you need to use for this specific problem is A = 3.14 · r².

A = (3.14) r²

A = (3.14) (4) ²

A = (3.14) (16)

A = 50.24
