Question

Radius of the circular track is 15/π cm and arc length is 10 cm.Find displacement?

Answer 1

here displacement means the angle displaced
let the angle displaced be x
radius be r
arc length be l

the formula is : x*r=l

X = l/r
= 10/(15/pi)
= 10pi/15

=
$10\pi \div 15 \: radians$
or
$0.666\pi \: radians$
is the answer
