# Hands around the World

You have a rope that will reach around the earth (about 25,000 miles or 40,000 km). If you put sticks of 1 meter high around the world and lay the rope on these sticks, how much longer will the rope need to be?

Assuming we can lay the sticks on the ocean surface:
The rope needs to be about (2 x 3.14159266)m longer

• Let’s instead assume that the sticks are one meter high–at sea level–around the world.

Hopefully that clarifies things a little.

Around 2 x Pi x 1 = 6.283 m

• Roolstar

6.283 m = 2 x Pi x 1

• 6.28 meters longer is correct!

The funny thing is, no matter what the original circle is, (it could be one meter, 100 meters or 1000 meters in radius) if you extend the radius by one meter, the rope gets 6.28 meters longer.

Great job, Rool, you’re today’s winner!!!
