A square with an area of 2 is inscribed in a circle. what is the area of the circle?
A) pie
B) Pie^2
C) 2pie
D) 2 radical pie
E) 4pie
It’s “pi,” not “pie.”
A square with an area of 2 will have sides of length , and therefore a diagonal of 2. (If you’re wondering how I know that, read up on special right triangles.)
If the square’s diagonal is 2, then the circle’s radius is 1, so the area is .
