Question

a boy is running along the circumference of a circular track whose radius is 35 metre find the distance covered by him to go four times round.​

Answer 1

distance covered by him to go four times round = 880m

Step-by-step explanation:

Circumference of circular track = 2πr

$= 2 \times \frac{22}{7} \times 35$

$= 2 \times 22 \times 5$

= 220m

distance covered by him to go four times round

= 4×220= 880m
