Answer:
16 cm
Step-by-step explanation:
Circumference of a circle
We are told that the string is wound symmetrically around a circular rod.
Now, the circumference of the rod is 4 cm and length is 12 cm.
Now, circumference is also the length of a circle. Thus, one wound of the string will be equal to the circumference of the rod.
Thus, one wound = 4 cm
Since the string makes 4 turns about the rod, then;
Length of string = 4 × 4 = 16 cm
