Question

The diameter of the wheel of a cart is 1.05 m.How much distance will the cart cover in 1000 rotatios of the wheel ?

Answer 1

1 rotation is equal to circumference =
Now circumference of circle = 2πr or πd

So circumference = π × 1.05
= 3.29867

Now as the cart covered 1000 rotations, the distance is 3298.67 m.(approximately = 3299.)

Answer 2

circumference of wheel   = (22*d)/7

here,  circumference of wheel = (22*1.05)/7  = 3.3 m

it means that the wheel covers 3.3 m  in one rotation,

it will cover 1000 *3.3  in 1000 rotations

it will cover 3300 m  in 1000 rotations




i hope this will help you
