Solution

The distance covered by the dog after one revolution about the pole is nothing but the circumference of the circle.
Circumference of the circle = $2 π$ r
Here, r is the length of the rope = 49 m

Circumference = $2 \times \frac{22}{7} \times 49$
$= 308 m$
$∴$ The distance covered by the dog after one revolution about the pole is 308 m.
