Question

An athlete completes one round of circular track of diameter of 200m in 40s find the distance travelled by him and

Answer 1

Solution:-

Its given that,
Diameter=200m

So,
Radius=200/2
=>100m

Time =40 seconds.

He completes one round which is =circumference of circle

Since we know that,
Circumference of circle =
$= > 2 \times \pi \times r \\ = > 2 \times \frac{22}{7} \times 100 \\ = > 628.57$
Hence,
Distance travelled by him is 628.57m.
