radius = 14 cm
circumference= distance covered in 12 hours = 2*22/7*14= 88cm
in three days
no. of hours = 3*24= 72
no. of 12 hours = 72/12= 6.
distance covered in 3 days = 88*6= 528

Given: Hour hand = 14 cm long

To find: Distance outer tip will cover in 3 days

Radius of clock (r) = 14 cm

Circumference = 2πr (Distance covered in 12 hours)

= 2 × 22 × 14

7

= 88 cm

Now by using Unitary method,

No. of hours in 3 days= 3 × 24

= 72

No. of 12 hours = 72

12

= 6

Distance covered in 3 days = 88 × 6

= 528 cm

So 528 cm distance will be covered by its outer tip in 3 Days.
