What is the circumference of a circlee with a radius of 2.3?

The circumference of a circle can be calculated using the formula ( C = 2\pi r ), where ( r ) is the radius. For a circle with a radius of 2.3, the circumference is ( C = 2\pi(2.3) ), which is approximately ( 14.43 ) when using ( \pi \approx 3.14 ). Therefore, the circumference of the circle is about 14.43 units.
