The center circle of a soccer field prohibits a defender from being near the ball at the start or restart of a soccer game. On a professional soccer field this circle is 20 yards in diameter. Find the area of this circle. Show work or explain how you found your answer.
In terms of diameter (d), the area (A) of a circle is given by the formula A = (π/4)d²
You have d=20 yd, so the area of the circle is A = (π/4)×(20 yd)² . . . . substitute the given information into the formula A = 100π yd² . . . . . . . . do the arithmetic A ≈ 314.16 yd²
