Question

the diameter of A wheel of a car is 70 cm how many Revolution will it make to travel 99 km

Answer 1

$<b>Heya mate. (^_-). Solution below.$
====================================

[] Given diameter of the wheel = 70 cm



[] Then, circumference of the wheel

= πd (where π = 22/7 and d is the diameter.)

= 22/7 × 70

= 22 × 10

= 220 cm.



[] Now, revolutions made to cover 220 cm = 1


Therefore, revolutions made to cover 99 km = 99 × 1000 × 100 cm

= 9900000/220

= 45000


•°• The wheel will make 45000 revolutions to cover 99 km.
