In one revolution, car covers 1 circumference of a wheel
Circumference = pi * D, where D  is the diameter.
So 1 revolution =  42 * 22 / 7
= 6 * 22
= 132 cm

3.3 km = 3.3 * 1000 * 100 (1000 to convert to meters, 100 to convert to cm)
= 3.3 * 10^5 cm

Revolutions = 3.3 * 10^5 / 132
= 2,500 revolutions ... Answer
