WebCircumference formula. The ratio of the circumference to the diameter of any circle is a constant known as pi (π), which is equal to approximately 3.14159. From this … WebJul 3, 2024 · You can calculate the circumference of any circle if you know either the radius or diameter. The formulas are: C = πd C = 2πr where d is the diameter of the circle, r is its radius, and π is pi. So if you measure the diameter of a circle to be 8.5 cm, you would have: C = πd C = 3.14 * (8.5 cm) C = 26.69 cm, which you should round up to 26.7 cm
WebThe formula for the area of a circle is equal to πr², where r is the radius of the circle. If the radius is given, we need to square it and multiply it by π to find the area of the circle. If the diameter of a circle is given instead of its radius, we need to divide the diameter by 2 to find the radius, then proceed as above.
