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
