The area of a circle is given by the formula A = πr^2, where r is the radius of the circle.
In this case, the radius of the sprinkler is given as 4 feet.
Therefore, the area that the sprinkler can cover is:
A = π(4^2)
= π(16)
≈ 50.27 square feet
Therefore, the closest choice to the area of lawn that the sprinkler can cover is 50 square feet.
