Given
Radius = 14cm
Time = 40 sec
3 min = 180 seconds
Total number of revolution = 180/40 = 4.5 revolution
Distance
Distance traveled in one revolution is 2πr
Distance traveled in 4.5 revolutions is 4.5x2πx14
Answer = 395.8 cm
Displacement
Final and initial position difference = half revolution = diamter
answer = 28 cm
