To do: To find the distance run by a boy in making $4$ complete rounds.
Solution:
Radius of a circular field$=24.5\ m$
Distance to cover the circular field in one round$=$Circumference of the circle
$=2\pi\times r=2\times \frac{22}{7}\times 24.5=154\ m$
$\therefore$ Distance run by the boy in making $4$ rounds$=4\times 154\ m=616\ m$
