Question

find the distance covered by a tyre of a car of radius 28 cm. in revolution​

Answer 1

Answer:

2*22/7*28 = 176cm. No. of revolutions = 1000. Therefore, Distance covered in 1000 revolutions = (176 * 1000) = 176000cm,or 1760m,or 1.76km

Step-by-step explanation:

Answer 2

Answer:

Distance covered by a tyre of car in one round = circumference of the Tyre

using

circumference = 2πr (where r = Radius of tyre)

=> distance covered = 2× 22/7 × 28

=> distance covered = 176
