Question

A person travels in a circular path of radius ‘r =14cm’. The distance and displacement covered by him after completing 1.5 rounds is​

Answer 1

Explanation:

r=14cm

distance = 1 round + ½ round

$= 2\pi \: r \: + \pi \: r \: = 3\pi \: r \\ = 3 \times 22 \times 14 \div 7 \: \\ = 134 \: cm$

displacement = diameter =2r =2×14cm =28cm
