Question

A cylinder of circumference 5 cm is rolling without sliding at a rate of 4 rounds per second. in 3 sec the cylinder will roll a distance of?

Answer 1

Answer: *60cm*

Step-by-step explanation

Distance covered in 1 round = 5cm

Distance covered in 1 second = 5 × 4 = 20cm

Distance covered in 3 sec = 20 × 3 = 60cm

Answer 2

In 3 sec the cylinder will roll a distance of 60 cm

Step-by-step explanation:

Circumference of cylinder = 5 cm

Distance covered in 1 round = 5 cm

Distance covered in 4 rounds =$5 \times 4 = 20 cm$

Time taken to complete 4 rounds = 1 sec

Time taken to complete 20 cm = 1 sec

Distance covered in 1 sec = 20 cm

Distance covered in 3 sec = $20 \times 3 = 60 cm$

Hence in 3 sec the cylinder will roll a distance of 60 cm
