The formula of circumference of a circle is 2 pie r, where value of pie is 3.14 and 'r' refers to the radius of the circle. So. By formula, 2 pie r = 180 means r= 90/pie i.e., r= 28.66 now diameter of a circle is twice its radius. Therefore, diameter is 28.66 * 2 = _____ feet please calculate yourself. The formula is absolutely correct. But please recheck the calculations. And please pray for my well being.
