How to Calculate the Circumference of a 50 cm Diameter Circle

Learn how to calculate the circumference of a circle with a 50 cm diameter using the formula C = πd.

20 views

The circumference of a circle can be calculated using the formula C = πd, where π is approximately 3.14159 and d is the diameter. For a circle with a 50 cm diameter, the calculation is C = 3.14159 * 50, resulting in approximately 157.08 cm. Remember to use π to as many decimal places as required for precision.
