The average radius of the Earth is 3,959 miles.
The equitorial diameter of the Earth is about 7,926 miles.
The ratio of the circumference to the diameter of a circle is written as the symbol pi.
Pi is approximately 3.141592.
Therefore, to determine the circumference from the diameter given above:
equitorial diameter x 3.141592 = equitorial circumference
=
7,926 x 3.141592 = 24,900
=
The earth has a circumference of approximately 24,900 miles.
More precisely the circumference of the earth
at the equator is 24,902 mi.
Remember that the earth is not a completely rounded sphere.
The Earth is 3.64 times larger than Moon's Circumference. (Earth's Circumference) 39,843 divide by (Moon's Circumference) 10,921=3.64
The circumference of Earth at the equator is about 24,874 miles.
== == Given that the circumference of the earth is 40,075.02 km (measured at the equator) the circumference in inches is roughly 1,577,756,664 inches.
The equatorial circumference of the earth is 24901.45 miles (40075.02 km).
Circumference of the earth at particular latitude can be determined using the formula, Circumference of the earth = 2*PI*r*cos(Φ0) where r = radius of the at particular latitude r = R * (1 - ((1 / 298.25722356) * (0.5 - 0.5 * COS (2 * Φ0)))) R= radius of the earth at equator Φ0= latitude
To calculate the circumference of the Earth, you can use the formula C 2r, where C is the circumference, is a constant (approximately 3.14159), and r is the radius of the Earth. The average radius of the Earth is about 6,371 kilometers. Plug this value into the formula to find the circumference.
Best guess for Earth Circumference is 24,900 miles (40,080 km)
The circumference of the Earth at the equator is 24,902 miles. From pole to pole is 24,860 miles.
Multiply the diameter by pi to find the circumference
The circumference of the earth in miles is about 24,901 miles. The diameter is about 7,926 miles.
Earth's circumference is greatest at the equator, where it measures approximately 24,901 miles (40,075 kilometers). This is due to the Earth's shape being an oblate spheroid, which means it bulges at the equator and is flatter at the poles.
