The perimeter of a square with side r
Webb6 apr. 2016 · This gives the square's area as A = s 2 = ( 2 r) 2 = 4 r 2. So, using our mental flexibility and analogous measurements of each object, we get the square's area as A = 4 r 2 and the circle's area as A = π r 2. Now imagine we have a square and a circle, each with the same r. Let's let r = 1. Webb31 okt. 2024 · For a circle with radius r, a square with the same area will have a side length of r√π. So, for example, if a given circle has a radius of 10 cm, then a square with the same area as the circle will have a side length of 10√π cm. Alternatively, we can also convert a given square to a round shape by doing the reverse operation.
