WebMar 27, 2010 · The circumference is the distance around a closed curve. The formula for circumference is C= pi x d. The diameter is two times the radius (d= 2r or r= d/2). The value of pi is approximately 3.14. The formula for the area of a circle is A= Pi x r^2. This video provides examples and demonstrations on how to use and solve with both the formulas. 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
