Answer 2

Step-by-step explanation:

Radius of wheel = 35 cm

Circumference of wheel = 2Πr

                                       =  2*22/7*35

                                       =   220 cm = 2.2 m

The wheel must rotate to complete 880 m                                        

So no. of rotations = 880/2.2

                               = 400 rotations

A wheel of radius 35 cm takes 400 rotations to complete 880 m.

Hope it helps
