Question

An athlete moving on a circular track of 100 metre radius if complete two and half round of this trak then calculate the distance travelled and displacement covered by athlete

Answer 1

• distance = 2 x 2πr + πr

= 2 x 2x 3.14 x 100 + 3.14 x 100

= 1256 + 314

= 1570m

• displacement = radius of the circle

= 100m

hope this answer will be helpful to you dear.
