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

How to Find the Circumference of a Circle Using Its Area

WebAug 2, 2024 · If you know the area of the circle, divide the result by π and find its square root to get the radius; then multiply by 2 to get the diameter.

WebOct 23, 2011 · The equation for the circumference of a circle can be written in two ways: C = 2πr C = πd Where: r represents the radius of the circle, and d represents a circle's diameter. Recall that the radius is the distance from the center of the circle to a point on the edge of a circle, and the diameter is the largest distance across a circle. WebThe standard equation for a circle centred at (h,k) with radius r is (x-h)^2 + (y-k)^2 = r^2 So your equation starts as ( x + 1 )^2 + ( y + 7 )^2 = r^2 Next, substitute the values of the given point (2 for x and 11 for y), getting 3^2 + 18^2 = r^2, so r^2 = 333. The final equation is (x+1)^2 + (y+7)^2 = 333 Hope this helps!
