Question

a minute hand of clock is 10 cm long find its distance and displacement from 7 am to 7:30 pm​

Answer 1

Step-by-step explanation:

distance= (Perimeter of circle/2)

distance={(2πr)/2}

distance={πr}

distance={(22/7)×10}

distance= 31.428 cm^2

displacement=2×(Radius)

displacement=2×(10)

displacement=20cm
