Question

A man moves in a circular whose radius is 100m. calculate the total displacement and distance covered by a person when it is diagonally opposite of circular path​

Answer 1

Answer:

$it \: is \: given \: that \: he \: has \: travelled \\ \: half \: of \: the \: circle \: then \: the \: distance \\ \: travelled \: by \: man \\ \: will \: be \: semicircle \: \\ distance = \frac{1}{2} \times 2\pi {r }^{2} \\ = \pi {100 }^{2} \\ = 10000\pi {m}^{2}$

Explanation:

$displacement \: is \: the \: shortest \: distance \\ displacement \: will \: be \: the \: diameter \: of \: circle \\ displacement = 2 \times r \\ = 2 \times 100 \\ = 200$

Answer 2

Answer:

displacement will be 0

distance =1/2×100=50
