What is the circumference of a circle with a radius of 7?

The formula for the circumference ( C ) of a circle is given by the equation ( C = 2\pi r ), where ( r ) is the radius of the circle. In this case, the radius is given as 7.

By substituting the radius into the formula:

[

C = 2\pi(7) = 14\pi

]

Thus, the calculation shows that the circumference of the circle is ( 14\pi ). This aligns with the provided answer. Calculating based on the established formula for circumference ensures accuracy and clarity in understanding the properties of circles.
