Radius squared pi
WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd. WebThe formula to find the area of a circle is to square the radius and multiply by π. The inverse of this is divide the area by π, then square root. 900π ÷ π = 900. The square root of 900 is …
