Question

A man running on a circular track of radius 5m. when he Completed one lap He stooped.A)What is distance travelled by man?B)WhaWhatis displacement?​

Answer 1

• Radius=5m=r

Distance travelled=Circumference

We know

$\boxed{\sf Circumference=2\pi r}$

$\\ \sf\longmapsto Circumference=2\times \dfrac{22}{7}\times 5$

$\\ \sf\longmapsto Circumference=\dfrac{220}{7}$

$\\ \sf\longmapsto Circumference=31.4m$
