A square is a quadrilateral with all four sides equal and all four corners at right angles.

Its two sets of opposite sides are parallel, all four sides are equal, and the four corners are 90°; Diagonal.

Perpendicular, bisected and equal to each other, each diagonal is bisected by a set of diagonals, which is a special form of a rectangle and a special form of a rhombus.

There is a set of parallelograms with equal adjacent edges and one angle at a right angle.

It's called a square.

A quadrilateral with all four sides equal and all four corners at right angles is a square.

The two opposite sides of the square are parallel to each other, and all four sides are equal; All four corners are 90°; The diagonals are perpendicular, bisected, and equal to each other, with each diagonal bisecting a set of diagonals.

A group of parallelograms with equal adjacent sides and one corner at right angles is called a square. There is a group of rectangles with equal adjacent sides called squares, and there is a diamond with an angle of 90° called a square. The square is a special form of a rectangle and a special form of a diamond.

The square of the side length is the square area. So the side length is: 8 open root number, get 2 times the root number 2, about cm

Is your complete problem to draw the largest circle in a square with an area of 8cm, and find the area of the circle?

If yes it would be nice :

Suppose the radius of the circle is x, and the side length of the square is 2x, and 2x is known to be 8cm, then the square of x (the square of the radius) is 8 4 2 (cm) then.

A: ......

Question: If a rectangle is reduced by a ratio of one to three, the area difference between them is 64 square centimeters, and the original rectangle is faced.

Answer: If a rectangle is reduced according to the ratio of one to three, and the difference in area between them is 64 square centimeters, what is the area of the original rectangle?

The solution is as follows: the original area x, the area y after the shrinkage is small, and the area difference before and after the reduction ratio 3 is 64

x-y=64

x/y=3*3=9

x-y=64

x/y=9x+64=y

x=9y9y-y=64

y=8x-8=64

x=72A: The area of the original rectangular is 72 square centimeters.

The area of the small square is 64 square centimeters.

Look at the picture: 80 - the area of the small square in the lower right corner is 4 times 4 (yellow part), which is 16 square centimeters = 64 square centimeters.

64 square centimeters is the sum of the area of the rectangle with a width of 4 cm at the bottom left and the area of the rectangle with a width of 4 cm (red part) at the top right, so divide 64 by 2 = 32 square centimeters. This 32 square vertical closed centimeters is a red-shaded part of the area of a small rectangle. 32 divided by 4 = 8 cm is the length of the side of the blank square.

Then use 8 times 8 to get 64 square centimeters. The area of the small square is 64 square centimeters.

The rules of multiplication:

Digit alignment, starting from the right, use the number on each of the second factor to multiply the remainder of the first factor, and multiply to which digit you want, and the end of the number will be aligned with which digit of the second factor.

The difference between the ten digits of the two digits is 1, and the two digits of the single digit are complementary.

For example: 48 5212 2839 1148 3296 8475 65 is to use the square of the ten digits of the larger factor and subtract the square of its single digit.

Oral decision: large number of head squared - tail squared.

The area of a square is 8 square centimeters, and the side length is 2 roots and 2 centimeters.
