Question

An insect is crawling on a cycle rim of radius 14cm.what will be the distance and displacement of the insect in full complete revolution

Answer 1

full revolution (circumference)=2pir
=2×22/7×14
=88

Answer 2

$\setlength{\unitlength}{5 pt}\begin{picture}(10,10)\put(0,0){\circle{9 cm}} \put(0,0){\circle*{0.5}} \put(0,0.5){ \tt{O} }\put(1,-2){ \tt{14cm} }\put(0,0){\line(2,0){4}}\end{picture}$

FOR FULL REVOLUTION DISPLACEMENT IS ZERO. BECAUSE STARTING AND ENDING POINTS ARE THE SAME..

DISTANCE TRAVELLED IS

EQUAL TO THE

PERIMETER OF THE

CIRCLE=2πR=2 x22/7 x14

DISTANCE=88cm
