Answer:
distance traveled by the hands =circumference of the circle.
circumference of the circle produced by short hand=2πr=2×3.14×4=25.12cm
circumference of the circle produced by long hand=2πR=2×3.14×5=31.4cm
In 24hrs short hand completes 2 rotations and long hand completes 24 rotations
∴ the sum=2(25.12)+24(31.4)=803.84cm
hope it helps you!!!
