WebCircumference of a circle = 2πr. Formula 2: When the diameter of a circle is known. Circumference = πd. Formula 3: When the area of a circle is known, we can write the formula to find the perimeter of the circle as: C = √ (4πA) Here, C = Circumference of the circle. A = Area of the circle. WebSo if we take the principal root of 36, we get r is equal to 6. From there, we can use this to figure out the circumference. So the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we ...
