Question

Calculate the distance and displacement covered by a body if it moves along a circular paths of radius of 14cm for 2 3/4 revolution

Answer 1

Answer:

Explanation:

$Radius=14 cm\\Distance=2\pi r=2*\frac{22}{7}*14= 88 m\\\2\frac{3}{4}= \frac{11}{4}\\ Distance=\frac{11}{4}*88=242 m.$

Answer 2

Explanation:

The body moves along a circular path.

radius=14cm

perimeter of the circular path= 88cm

The body covers distance=88×11/4=242cm

displacement=88×1/4=22cm
