Suppose the radius of the earth is given to be 6378.01 km. Express the circumference of the earth in meters. At a certain distance above the earth's surface, the gravitational force on a certain object is only 2.8% of its value at the earth's...
Did you know that as early as the 200s BC, there were individuals who had calculated the measurement of the Earth's circumference? Using only math, the Greek astronomer Erasothenes was able to estimate the distance around the Earth using angles, shadows, and the Sun. Although his ...

Over 2000 years ago, the Greeks found the circumference of the Earth by looking deep into a well. Eratosthenes estimated the Earth’s diameter was approximately 8,000 miles. When you hold out a spherical object, Greeks also found through trial and error that a 1-inch diameter object cast a...
The further from the equator you go, the more inaccurate the scale becomes. 3. Now measure the length of the Equator on the world map in inches. ___ inches 4. To find out the circumference of the world at the Equator, (distance around the world at the Equator), multiple the scal...

(approaching πR, half the circumference) a small error is often not a major concern in this unusual case (although there are other great-circle distance formulas that avoid this problem). (The formula above is sometimes written in terms of the arctangent function, but this suffers from ...
2.Every point on the surface of a sphere is at an equal distance from its center.球面上的每一点到球心的距离都是相等的。 3.A point equidistant from all points on the circumference of a circle or on the surface of a sphere.圆心,球心与一圆周上或一球面上所有点等距的一点 ...
