Answer 1

1760m = 1.76km in 1000 revolutions.

pls mark me brainliest and follow me

Answer 2

Answer:

Radius of tyre = 28cm.

Circumference = 2*22/7 * r

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:

circumference of tyre = 2pie r =2 x22/7 x28 =176 distance covered one revolution =176 therefore distance covered in 1000 revolution =176 x 1000=176000
