The radius of a circle is 13 ft.Find its circumference in terms of pi Answer

The formula for the circumference \( C \) of a circle is given by:<br /><br />\[ C = 2\pi r \]<br /><br />where \( r \) is the radius of the circle.<br /><br />Given that the radius \( r \) is 13 ft, we can substitute this value into the formula:<br /><br />\[ C = 2\pi (13) \]<br />\[ C = 26\pi \]<br /><br />Therefore, the circumference of the circle in terms of \( \pi \) is \( 26\pi \) ft.
