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

$C = \pi * d$

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:

$C = \pi * 8 \ cm$

ANswer:

Option C

$8 \pi \ cm$

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

$\frac{422}{59}\approx7.15$
You have to round it up. So it will be 8 shelves.
