As we know the CIRCUMFERENCE:- 2πr
Here r belongs to radius which is equals to = diameter/ 2
Here in the given picture the diameter is 14 so the radius will be 7 .
Now CIRCUMFERENCE = 2× π × 7
= 14π
But we habe to findonly the number which is suitable for the given box so there will be 14 in the box
So 14 is the correct answer .
HOPE IT HELPED YOU.
