Question

an athlete complete one round of a circular track of diameter 200m in 20s . calculate. (1)distance travelled by the athlete. ​

Answer 1

Answer:

Explanation:

Solution,

Here, we have

Diameter = 200 m

Radius, r = 200/2 = 100 m

Time taken, t = 20 seconds

To Find,

Distance traveled = ?

Here, we have

Distance traveled, means the circumference of circle,

We know that,

circumference of circle = 2πr

So, putting all the values, we get

Distance traveled = 2πr

⇒ Distance traveled = 2 × 22/7 × 100

⇒ Distance traveled = 4400/7

⇒ Distance traveled = 628.57 m

Hence, the distance traveled by the athlete is 628.57 m.
