Circle Inside A Square 12m = rθ = r arctan(3 2), (3) where r is the radius; thus. r = 12m arctan(3 2); (4) the side of the square is 2r; the area is thus. 4r2 = (2r)2 = 576m2 arctan2(3 2); (5) since 1m = 100cm, 1m2 = 10, 000cm2, so the area becomes. 5, 760, 000cm2 arctan2(32). (7) theory is easy; it's arithmetic that's hard!. Area of square inside a circle a = 2 r 2. where r is the radius of the circle, and also the distance from the center of the square to one of its corners. finding the area of the circle that is not inside the square (the part of the circle shaded green below). the formula for the area of a circle is a = π r 2.

Square Inside A Circle Conversely, we can find the circle's radius, diameter, circumference and area using just the square's side. problem 1. find formulas for the square's side length, diagonal length, perimeter and area, in terms of r, the circle's radius. strategy. the key insight to solve this problem is that the diagonal of the square is the diameter of the circle. Let's assume the length of the side of the square to be 10 units. ⇒then, by using the pythagoras theorem, we get the length of the diagonal, which is also the diameter of the circle (according to the properties of circle). ⇒therefore, diameter of circle = diagonal of square = √ (10 2 10 2) = 10√2 units. ⇒hence, the radius = diameter. A square has a length of 12cmthe area of the square if 12x12=144the area of the circle is pi*6^2=36piview my channel: jayates79. The difference between them is the 4 corner shapes formed by two edges of the square and an arc which is a quarter of the circle. from symmetry, all these shapes have equal area. so the shaded region is half the difference between the areas of the circle and the square. solution. a square =a·a=10·10=100 a circle = π·a 2 4=π·10 2 4=25π.
