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.
