To find the circumference of a circle, use C = 2πr or C = πd. To find the diameter, use d = 2r. The radius is half the length of the diameter.
To find the circumference of a circle, you can use the formula C = 2πr or C = πd, where r is the radius and d is the diameter. The radius is the distance from the center of the circle to any point on the edge, while the diameter is the distance across the circle passing through the center. The circumference is the total distance around the circle.
To find the diameter of a circle, you can use the formula d = 2r, where r is the radius. The diameter is always twice the length of the radius, or the distance across the circle passing through the center.
The radius of a circle is the distance from the center to any point on the edge. It is half the length of the diameter, so you can find the radius by dividing the diameter by 2. If you know the circumference or diameter of a circle, you can find the radius by using the formulas r = C/2π or r = d/2.
