1.
The larger gear will have turned through an arc equivalent in length to the smaller circle's circumference. Thus:
2πr(small) = r(large)∅
2π(2) = 8∅
∅ = π/2 = 90°
2.
The distance covered by the larger gear will be:
C = 2πr
C = 2π(8)
C = 16π
Per revolution, the smaller wheel covers:
C = 2πr
C = 2π(2)
C = 4π
Number of revolutions of smaller wheel = 16π / 4π
Number of revolutions = 4
