Rope Around The Earth Add 10 Feet

40 000 divided by 2 is 20 000.

Rope around the earth add 10 feet.

All around the earth the rope is raised up uniformly as high as is possible to make it tight again. Multiply by 2 to get. Difference of diameters is 0 95 feet. If you put 1 metre high sticks right around the equator and lay the rope on.

3 foot diameter 41 851 445 75 feet. You add an extra 3 feet to the length. 3 footcircumference 131 480 194 53 feet. The radius of earth is 6371 km approx.

All around the earth the rope is raised up uniformly as high as is possible to make it tight again. Suppose you tie a rope tightly around the earth s equator. 15cm that s how far off the ground we re lifting the string remember out of 6 370km is close. Suppose you tie a rope tightly around the earth s equator.

Divide by 2 pi to get. Rope around the earth consider the earth to be a perfect sphere. Now let us tie a rope tightly around its equator. Divide that by 2 to get how high off the ground the rope is all the way around the earth.

In fact this brain teaser requires neither an exact measurement of the earth s circumference which in fact varies by many kilometers depending on which circumference you measure nor even an assumption that the earth has a circular cross sect. If the extra rope is distributed evenly around the globe will there be enough space between the rope and the surface of the earth for a worm to crawl under. 3 foot radius 20 925 722 88. Subtract larger of the two diameters from the smaller.

Student answer form blackline master rope around the world you have a piece of rope that just fits around the earth. Divide again by pi to get the earth s radius 6 370km. Suppose you tie a rope around the earth at the equator circumference approx.
