The formula to calculate the circumference of a circle is given by:
Circumference = 2πr, where r is the radius.
Substituting the given value of r = 9 cm and using π = 3.14, we have:
Circumference = 2 * 3.14 * 9 cm
Circumference = 56.52 cm.
Therefore, the circumference of the circle is 56.52 cm.
The radius of a circle measures 9 cm. What is the circumference of the circle?
Use 3.14 for n, and do not round your answer. Be sure to include the correct unit in your answer.
