What is the circumference of a circle with a radius of 5?

The circumference of a circle is calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. In this case, the radius is 5. By substituting the radius into the formula, we get:

[

C = 2\pi(5) = 10\pi

]

This demonstrates that the circumference of the circle with a radius of 5 is indeed ( 10\pi ).

Other options propose different multiples of ( \pi ), which are not derived from the correct application of the circumference formula using the given radius. Therefore, the correct calculation leads to the choice that corresponds with ( 10\pi ) as the precise circumference of the circle.
