Question

Hi!

got a question!
A wheel of radius 14cm went round 1000 times ,what distance did it cover in km?
Give your answer to 2 decimal places.​

Answer 1

Radius = 14 cm = 0.00014 km

Circumference = 2πr = 2 × 22/7 × 14/100000 = 0.00088 km

As it went thousand times , distance covered = 0.00088 × 1000 = 0.88 km
