WebFinding the area of a circle from the radius is the most common approach for computing the area of a circle. However, it is possible to find the area of a circle from its circumference. The circumference of a circle is given by the formula. C = πd = 2πr, where C= circumference and d= diameter. Thus r = C2 × π.
WebFrom 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.
