Question

A diameter of bicycle wheel is 63 cm find how many time it will revolve to cover 99m

Answer 1

hye

==========================

diameter is 63cm

we know that radius = d/2

r = 63/2

 r =  31.5 cm

circumference = 2πr

                        =  2 *22/7*31.5

                     =  198 cm


no. of turns=distance to be covered/circumference

                 = 198 / 99
      
                    = 2 turns

================================

hope it helps u...........
