.... and you want to know how much longer the second rope is than the first one?
If we take 4,000 miles as the radius, and we want to do any comparison with feet then we need to convert the miles to feet. There are 5,280 feet in a mile, and I'll use 3.1416 as the value of pi.
So, rope A goes around a circle with a radius of 4,000, which is a radius of 21,120,000 feet.
Then rope B goes around a circle with a radius of 21,120,010 feet.
As the circumference = 2 pi r we can multiply both of these by 2 pi and subtract the smaller from the larger.
Rope A = 132701184 feet
Rope B = 132701246.832
The difference here is 62.832 feet.
However, we can get exactly the same result if we just multiply the extra 10 feet by 2 pi = 10 x 2 x 3.1416 = 62.832. This is equal to 62 feet 10 inches.

How high is a three story house?
Each "story" would average around 9-10 feet, possibly more. Add the height that the structure starts out of the ground, and add the height of the roof (which can vary significantly).
What is the elevation of your house?
It can mean the height from the ground to the roof peak, or the ground elevation above or below sea level.
A cable is attached to the top of an 80' pole and to a stake in the ground 35' from the base of the pole What angle will the cable and the ground form?
66
A cable 48 feet long stretches from the top of a pole to the ground If the cable forms a 40 angle with the ground which is closest to the height of the pole?
26.4
How does the angle of launch affect the range and trajectory of the projectile?
Easy . Think of it like this. The higher you angle your catapult (or whatever your using.) The higher it will travel but it will have less power. If you have a lower angle you will have more power but it your projectile will hit the ground first. If you don't understand just play around with a slingshot and an empty can of soda. Or you could test it out this theory by playing around with angry birds ;)
Why is the equator imaginary?
It is a concept, not a physical thing. There is no line painted on the ground and ocean to show where the equator is, just as there is no line on the ground to show a state line.
What color is the equator?
The equator is an imaginary line. If you stood and looked at the ground at the equator, you would see....ground. The equator is not a mark on the surface of the Earth. On maps and globes it is usually a black line.
What happens to the air at the equator?
At the equator, warm air rises due to intense heating, creating a low-pressure zone. As the air rises, it cools, condenses, and produces heavy rainfall. This process contributes to the formation of tropical rainforests near the equator.
What is warmer near the equator than near the poles?
The equator is the center of Earth. In the center of the Earth it is very hot because of all of the under ground volcanoes.
Where exactly can iron be found?
in the ground as as iron oxide
How many meters is it from the ground to the atmosphere?
The atmosphere begins at the ground. The distance between them is exactly zero.
What is the distance from the earths ground level to the troposphere?
the distance of the troposphere from the Earth is about 17km from the equator and 5-6km from the poles
Why is the floor on the ground?
well because its not exactly gonna be on the celing
Which item will drop faster?
objects dropped exactly at the same moment will hit the ground (on earth) at exactly the same moment.
Where exactly does the red ant live in the Amazon rainforest?
they barrow in the ground
Is a real winter supposed to be about having snow on the ground each winter day?
A 'real' winter is whatever winter you've got, in some places there is snow on the ground and in other places it's just cold and nasty. Other winter seasons, for instance around the equator, are very mild.
What is the difference between the celestial equator and the horizon?
The celestial equator is an imaginary line in the sky that represents the projection of Earth's equator onto the celestial sphere. It divides the sky into northern and southern hemispheres. The horizon, on the other hand, is the line where the sky meets the Earth's surface when viewed from a specific location, forming the boundary between the visible sky and the ground.
