[size=100]A zookeeper recently opened a new turtle exhibit at his zoo. The radius of the inside of the swimming pool, the radius of the outside of the swimming pool, and the distance from the center of the pool to the midpoint of any of the square exhibit's sides forms the ratio 1:3:4.[/size]

[size=100]1a) In terms of pi, what is the area of the square exhibit that is designated for grass if the radius of the inside of the pool is 1 meter?[/size]

1b) In terms of pi, what is the area of the square exhibit that is designated for grass if the radius of the inside of the pool is 2 meters?

1c) In terms of pi, what is the area of the square exhibit that is designated for grass if the radius of the inside of the pool is 4 meters?
