What is the exact circumference of the circle?

2π cm
4π cm
8π cm
16π cm

circle with center d and diameter of 8 cm labeled.

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

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:

ANswer:

Option C

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
