Math word problem

A small circular pool is enclosed in a square. Find the area inside the square but outside the circle?
(of the shaded region). There is a picture of a square, which is shaded, around a circle. The circle is touching all four sides of the square and there is 4.3m above the square. How do I find the area of the circle with only knowing the length of the four sides of the square?

Isn't the diameter 4.3 m? Using that, find the area of the circle. But the square is 4.3 to a side, so compute the area of the square. Now for the inside, subtract the circle area from the square area.

The square measures 4.3 m on each side. Therefore, the diameter of the circle is 4.3 m.

Looks like they are saying, each side of the square is 4.3
Doesn't that make the diameter of the circle also 4.3, and its radius 2.15 ?
So take the area of the square, and the area of the circle, then subtract the two. 
Whamm!
Triple within two minutes. 
And we all agreed!!!!!

Thank you all. You guys are awesome. So i find the area of both and just subtract the circle from the square. Perfect!
