Find the circumference of a circle with a radius of $4$ units.

Answer 1

Abigail Nelson

Christopher Garcia

To find the circumference of a circle, we use the formula:

$ C = 2\pi r $

Given that the radius \( r = 4 \) units, we substitute this value into the formula:

$ C = 2 \pi \times 4 $

$ C = 8 \pi $

Therefore, the circumference is \( 8\pi \) units.

Answer 2

Alex Thompson

Emily Hall

The circumference ( C ) of a circle can be calculated using the formula:

$ C = 2pi r $

Here, the radius ( r ) is ( 4 ) units. Plugging in this value:

$ C = 2 pi imes 4 $

$ C = 8 pi $

Hence, the circumference is ( 8pi ) units.

Answer 3

Amelia Mitchell

Charlotte Davis

The formula for the circumference is:

$ C = 2pi r $

With a radius of 4 units:

$ C = 2 pi imes 4 = 8pi $

The circumference is ( 8pi ) units.
