The length of hour hand = 4 cm.
The distance covered by it in one day =2 π r= 2*3.14*4
= 25.12cm
The distance covered by it in 27 days = 25.12*27=678.24cm
Similarly, the length of minute hand = 5 cm
The distance covered by it in one day =2 π r= 2*3.14*5
=31.4cm
The distance covered by it in 2 7days =31.4*27= 847.8cm
The sum of distances travelled by them in 27 days
= 678.24cm + 847.8cm = 1526.04 cm ans
