A fly wheel rotates at 300 rev/min.if the radius is 6cm through what total distance does a point on the rim travel in 30 sec.

Answer 1

Circumference = pi*2r = pi * 6cm = 37.7
cm

d = 300rev/min * 37.7cm/rev * 0.5min =
18.85 cm.

Note: 0.5 min = 30 sec.

Answer 2

Correction: Change 6 cm to 12 cm.
The results does not change.

Answer 3
