If the square fits perfectly in the circle, the diameter of the circle (d) will equal the diagonal of the square. The diameter equals two radii.
d = 2 * r = 2 * 3√2 = 6√2
Therefore the diagonal of the square is 6√2 units long.
Then, from Pythagorean theorem, the side length (s) squared plus the side length squared equals the diagonal squared.
(s)^2 + (s)^2 = (6√2)^2, then simplify by combining the s terms
2(s^2) = (6√2)^2, then take the square root of both sides
√2 * s = 6√2, then divide both sides by √2
s = 6
So your side length is 6. The area (A) of a square is side length squared, and the perimeter (P) is 4 times the side length.
A = 6 * 6 = 36
P = 6 * 4 = 24

That sounds easy enough.
1. Draw a diagram. Draw a radius going from the centre of the circle to one of the corners of the square. Call this point a. Call the centre of the square b.
2. Draw a line from the centre to the middle of one of the sides of the square. The point where this line meets the square is called c.
3. Note that c to a is the same length as c to b. Now, you know a to b, so calculate a to c and b to c.
4. Calculate the area and perimeter of the square.

I couldn't get which one you meant so here are two different answers: If the circle is inside the square: Radius is 1 so one edge of square is 2 and area of square is 4. Then area of circle is 3x1^2=3. 4-3=1 so the answer is 1/4 If the square is inside the circle: One diagonal line of square is 2 so one edge is \/2. Area of square is \/2x\/2=2. Area of circle is again 3. 3-2=1 so it is 1/4 again

Diameter of circle = 6 x root 2 = diagonal of square
let sides of square be x-:
(6 x root 2)² = x² + x²
36 x 2 = 2x²
72 = 2x²
36 = x²
x = 6
Area of square = 6 x 6 ft² = 36 ft²

This means that the distance from the center of the square to one corner will also be 3 times the square root of 2.
That forms the diagonal of a right triangle. You have learned the pythagorean theorem.
a2 + b2 = c2 (sorry, I can't write squared the right way.)
a and b are each the same because they are half the length of one side. So a2 + a2 = c2 where c is 3 times the square root of 2.
a2+a2 = 2 a2 So 2 a2 = 9 times 2 (by taking 3 times the square root of 2 times itself.) 2 a2 = 18 So a2 = 9 So a = 3
Since half the length of one side is 3, each side of the square is 6, so the area is 36 square units.

yeah you sure do. answer is 2pix4.5square to the power of 3.14
I don't want to brag but I didn't even use a calkulator I used me fingers to work this one out.
