A cylinder whose base of circumference is 6 m can roll at a rate of 3 rounds per second. How much distance will the cylinder cover in 9 seconds?

163 m

165 m

162 m

168 m

Distance covered in one round = 2 x π x r =6 m
Distance covered in 1 second = 3 x 6 = 18m
So distance covered in 9 seconds = 18×9=162m
