The circumference of a circle is given by the formula C = 2πr, where r is the radius and π (pi) is a constant approximately equal to 3.14.

Substituting the given value, we get:

C = 2πr = 2 × 3.14 × 5 cm = 31.4 cm (rounded to one decimal place)

Therefore, the circumference of a circle with radius 5 cm is approximately 31.4 cm.
