Answer:

Shortest distance = 6

Step-by-step explanation:

The radius of the cone will be 1

Thus, the circumference of cone = 2π

Unfolding the cone  will result in a sector with radius 6 and circular circumference 2π. Labelling the center O  and the other two vertices A and B.The full circle has a circumference of 12π, thus the sector is a 2π/12π × 360° = 60°

Thus, the sector is 60°, so that ABO will be an equilateral triangle and the shortest distance will be AB = 6. Thus, The length of the shortest path for the ant to move around the surface of the cone without ever leaving it and return to its original position is 6.
