Answer:

approximately 18.85 cm.

Explanation:

So let's start with the basic understanding of circumference. Circumference is the perimeter of a circle. It's formula is:

C=2 x pi x r or C= pi x d

So in your case the diameter is 6

2) Plug it into the formula:

C = pi x 6

The exact answer would be 6pi, but with rounding it would be approximately 18.85 cm. :D

Answer:

C = 18.85 cm

Explanation:

The circumference of a circle is given by

C = pi*d

Where d is the diameter and

C = pi * 6

Using the pi button ( or3.141592654)

C = 18.84955592 cm

To the nearest hundredths place
