Question 2 If ๐ is taken as 22/7, the distance (in metres) covered by a wheel of diameter 35 cm, in one revolution, is (A) 2.2 (B) 1.1 (C) 9.625 (D) 96.25
Diameter = 35 cm
Radius = ๐๐/๐ cm
Now,
Distance covered in one revolution = Circumference of wheel
= 2๐r
= 2 ร 22/7 ร 35/2
= 110 cm
Converting into metres
=110/100 m
= 1.1 m
So, the correct answer is (B)
