Answer:

1) 500 turns

Step-by-step explanation:

d = 2.1m = 2r

circumference = 2πr = (22/7)×2.1 = 6.6m

so, number of turns = (3.3 × 1000m)/6.6 = 500

Given,
Diameter of wheel = 2.1 m
Distance = 3.3 km = 3300m

Solution,
Distance cover by a wheel in one turn = circumference of wheel

Circumference = 2 πr
= 2*(22/7)*(2.1/2)
= 22/7 *2.1
=22* 0.3
=6.6m

Turns in 3300m = distance/(distance cover in one turn)
=3300/6.6
=33000/66
=1000/2
=500
It will take 500 turns to cover the distance of 3.3km (3300m).
