Question 1159566: 6) A square rock garden with sides of 120 feet is placed in the middle of a circular grass yard. If the circumference of the yard is 500 feet, then how much area is covered by grass?
For all calculations involving π, use π ≈ 3.14.
Hint: Be careful that you do not do any rounding on answers until the very end of a problem part, or you could create rounding error.
a) Amount of area covered by grass, measured in square feet = ____ square feet.
DO NOT TYPE COMMAS. Round your answer to 2 decimal places as needed.

You need the radius of the circle to be able to calculate the area of the circle.





The area of the grass is the area of the circle minus the area of the grass.







You can do the rest of the arithmetic. Don't forget that the number of square yards is the number of square feet divided by 27.
