Finding radius from circumference
WebIf you know the radius, it is straightforward to compute the other two. To find the radius from the diameter, you only have to divide by two: r=d/2 r = d/2 If you know the circumference it is a bit harder, but not too bad: r=c/2\pi r = c/2π Dimensions of a circle: O - origin, R - radius, D - diameter, C - circumference ( Wikimedia) WebNov 28, 2024 · Find the diameter of a circle with a circumference of 21.98 feet. To work on this problem, you will need the formula for finding the circumference of a circle using the diameter. \(C=\pi d\) First, fill in the given information. \(21.98=(3.14)d\) Next, solve the problem by dividing both sides by 3.14.
