Question

a boy travels half a circle along circumference of a circle of radius 50 m find the distance and displacement covered by the boy​

Answer 1

$\boxed {\red{\bold{ Solution : }}}$

circumference of circle = 2πr

= 2 × 22/7 × 50m

= 44/7 × 50m

= 2200/7m

distance covered by boy = 2200/7m ÷ 2

= 1100/7 m

$\boxed{\orange{\bold{ \frac{1100}{7}m}}}$
