The square has perimeter Ps equal to 4L (where L is the side length of the square) and L equal to √(As) (where A is the area and subscript 's' indicates we are talking about the area of the square). From this we can rearrange to 4√(As). The circle has perimeter Pc equal to π(2R) (where R is the radius of the circle) and R equal to √(Ac/ π) (where subscript 'c' indicates we are talking now talking about the area of the circle) or, the square root of the circle's area divided by pi. From this we can rearrange to 2π√(Ac/ π). Since we know the perimeters are equal, Ps = Pc; we can then put the right sides together to get 4√(As) = 2π√(Ac/ π). Through rearranging of this equation, we can reduce to 4As = πAc. As a ratio, this comes down to As:Ac à π:4.

Is the circumference of a square linear?
A square can't have a circumference. That's only for circles squares have area, volume, or perimeter.
How do you find the area of a circle inside a square?
all you do is find the area of the circle... if you mean find the squares area, find the area of the circle, and then the square's area and subtract the squares area to the circles area

How much is perimeter?
The perimeter is the measure of length of the boundary of a 2-dimensional object. The most common mathematical objects in this category are squares, rectangles, circles and triangles. The perimeter of a square = 4d (where d is the length of 1 side) The perimeter of a rectangle = 2l + 2w (where l is the length and w is the width) The perimeter of a circle = 2πr (where π is the mathematical constant pi and r is the radius. The perimeter of a circle is better known as the circumference) The perimeter of a triangle is the total length of all three sides.
