Question 1148756: A circular rock garden with a diameter of 50 feet is placed in the middle of a square grass yard. If the perimeter of the yard is 116 yards, 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 = Blank
square feet.
DO NOT TYPE COMMAS. Round your answer to 2 decimal places as needed.
b) Amount of area covered by grass, measured in square yards = Blank
square yards.
