For this case, we have that by definition, the circumference of a circle is given by:

[tex]C = \pi * d[/tex]

Where:

d: Is the diameter of the circle given by 2r, that is, twice the radius.

If we have a circle with a diameter equal to 8cm, then the circumference is given by:

[tex]C = \pi * 8 \ cm[/tex]

ANswer:

Option C

[tex]8 \pi \ cm[/tex]

Answer:

The correct answer is option 3). 8π cm

Step-by-step explanation:

Formula for circumference of circle

circumference  = 2πr   where r is the radius of circle.

It is given that, Circle with center D and diameter of 8 cm labeled.

To find the circumference

diameter = 8cm

radius = diameter/2 = 8/2 = 4

circumference  = 2πr

circumference  = 2 * π * 4 =  8π

Therefore the circumference of given circle is

The correct answer is option 3). 8π
