The circumference of a circle is given by the formula C = 2πr, where r is the radius of the circle.
Substituting the given radius r = 7 cm into the formula, we get:
C = 2π(7) = 14π cm.
Therefore, the circumference of the circle is 14π cm.
The radius of a circle is 7 cm. Find its circumference in terms of piπ.
