Question

A cyclist moves in a circular path and covers half of the circle of radius 7 m. calculate the displacement and distance.​

Answer 1

$\huge\bold{ANSWER~:}$

For this type of question :-

Distence = 2πr / 2 = πr

Displacement = 2r

Here radius 'r' = 7 m

Use formula :-

Distence :-

$= \pi r \\ \\ = \frac{22}{7} \times 7 \\ \\ = 22 \: m$

Displecement :-

$= 2r \\ \\ = 2 \times 7 \\ \\ = 14 \: m$
