The circumference of a circle is calculated using the formula C = πd, where C is the circumference, π is the mathematical constant pi (approximately 3.14159), and d is the diameter of the circle. In this case, the diameter is 4 meters, so the circumference would be C = π(4) = 4π meters. This simplifies to approximately 12.57 meters.

What is the circumference of a circle with a 25ft diameter?

Use the equation C = pi*d Substitute C = 3.14 * 25 C = 78.5 ft NB This is only an approximate value, because '3.14' is only an approximate valuer for 'pi' , but convenient to use. The other eq'n to use is C = 2 pi r Where 2r = d ( two radii equals one diameter ) . NB . 'radii' is the common noun plural of 'radius'. NOT 'radiuses'.
