Question
The sides of a square field are
12 meters. A sprinkler in the center of the field sprays a circular area with a diameter that corresponds to a side of the field. How much of the field is not reached by the sprinkler? Round your answer to the nearest hundredth.
THANK YOU!

so, what's the difference between the area of a 12x12 square and a circle of diameter 12?

First, get the area of the square field. The area of the square is side multiplied by side.
A = S x S
A = 12 X 12
A = 144 meters squared
Second, get the area of the circle formed by the sprinkler.
The circle is formed inside the square with a radius of 6 meters (half of the diameter which is 12 meters).
A = \pir^{2}
A = 3.14 x 6^2
A = 113.04 meters squared.
In order to get the not sprinkled area, subtract the area of the square by the area of the circle.
Not Sprinkled Area = 144 meters squared - 113.04 meters squared
the final answer is 30.96 meters squared
A = S x S
A = 12 X 12
A = 144 meters squared
