If you wrap a rubber band around a ball 10 cm in diameter, then lift the band 1 cm off the ball all the way around, the band will be 6.28 cm longer. If you wrap a rubber band around the earth (radius=6,378 km) and again lift it up 1 cm all the way around, how much longer is the rubber band?
a) 4,005 km longer
b) 6,280 km longer
c) 8,011 km longer
d) 6.28 cm longer
d) 6.28 cm longer
Let dd = the diameter of the ball.
The length of the rubber band is πdπd.
We lift the band x cm off the ball.
We have a new circle with diameter d+2xd+2x.
The length of the rubber band is π(d+2x).
The difference is: .π(d+2x)-πd=πd+2πx−πd=2πxπ(d+2x)−πd=πd+2πx−πd=2πx
Since x=1x=1 cm, the difference is: .2π≈6.282π≈6.28 cm.
Note that the diameter of the ball (d) drops out.
Whether the ball is a BB or the Sun, the difference is always 2π2π cm.
