PLEASE POST A STEP BY STEP ANSWER, UNNECESSARY AND WRONG ANSWERS WILL BE REPORTED

Answer 1

Answer:

Circumference = 2πr

Circumference = 2 × 22 / 7 × 2.5

Circumference = 110 / 7

Circumference = 15.714285

Circumference = 15.71

Distance covered = 15.71 × 1400

Distance covered = 21994m

Hope my answer helps you :)

Answer 2

Answer:

22000m

Step-by-step explanation:

2πr =2×22 by 7 × 2.5 = 110 by 7 m

the distance covered in 1400 revolutions

= distance covered 1 revolution × 1400

= 110 by 7 × 1400 = 22000m

hence, 22000m is will be answer
