Answer:6.284
Step-by-step explanation:
it is a ncert exercise problem for 11th
let the radius be 1.5cm
and we can say that 40 minute is the 2/3rd division of a haur
also 2/3rd of 360 degree is 240 degrees
240 DEGREE IS 4π/3
also we have that L[distance moved by the tip of the minute hand]
now L= radius x angle= 1.5 x 4π/3=6.284 cm
