What is the Circumference of a Circle When the Diameter is 18?
If the diameter is given, let us see how to calculate the circumference of the circle.
Answer: The circumference of the circle when the diameter is 18 is 56.52 units
Circumference of a circle is = 2 × pi × radius
pi (/(/pi/) is the mathematical constant whose value is approximated to 3.14
Circumference of a circle whose diameter 18
= 18* 3.14
