Answer 2

The distance covered is 15.072 km

Step-by-step explanation:

The diameter of the circular path is d = 400 m.

Hence, the radius of the circular path is

$r=\frac{d}{2}\\\\r=\frac{400}{2}\\\\r=200 m$

The circumference of the circular path is

$C=2\pi r\\\\C=2\cdot3.14\cdot200\\\\C=1256 m$

In one round the distance covered is equal to the circumference of the circular path.

Hence, the distance covered in 12 round is equal to

12 × C

=12 × 1256

= 15072 m

= 15. 072 Km
