PLEASE HELP ME QUICK!! A company produces circular drink coasters. The equation x2 + y2 = 18.0625, with units in inches, represents the size of a coaster. Each coaster is cut from a square piece of cardboard. What is the minimum possible area of each cardboard piece?

4.25 in^2
8.5 in^2
18.0625 in^2
72.25 in^2

7x+8y=-18, 4x-9y=-3 solve the system of equations

What is a rational number between 9.5 and 9.7
