How to solve the circumference of a circle
WebLetting the number of sides n tend to infinity, the polygon "tends" to a circle and we get that Area of the circle = Circumference × diameter 4 or to put it the other way around Circumference = 4 × Area of the circle diameter As you see from this, there is no need for π anywhere. Share Cite edited Jun 12, 2024 at 10:38 Community Bot 1 WebThe formula for the area of a circle is A = πr2. We are given the area, and by substitution we know that 13π = πr2. We divide out the π and are left with 13 = r2. We take the square root of rto find that r= √13. We find the circumference of the circle with the formula C = 2πr. We then plug in our values to find C = 2√13π. Report an Error
