What is the circumference of a circle with a radius of 3 cm? (Use π = 3.14)

To find the circumference of a circle, you can use the formula:

Circumference = 2πr

where r is the radius of the circle and π (pi) is approximately 3.14.

In this case, the radius given is 3 cm. Plugging the values into the formula:

Circumference = 2 × 3.14 × 3 = 6.28 × 3 = 18.84 cm

This calculation shows that the correct circumference for a circle with a radius of 3 cm, using π approximated as 3.14, is indeed 18.84 cm. The result clearly matches one of the choices provided, confirming that the computation follows the proper method to arrive at the circumference.
