please tell​

Answer 1

Answer:

6378 km

Explanation:

Its equatorial radius is 6378 km, but its polar radius is 6357 km - in other words, the Earth is slightly flattened. Eratosthenes was measuring the polar radius, and his value (using the 0.15 km/stadium conversion) lies between the polar and equatorial values.

Hope it helps u.Have a good day my friend!!!!

Answer 2

Answer:

Earth radius is the distance from the center of Earth to a point on its surface. Its value ranges from a near maximum 6,378 km (3,963 mi) at the equator to a near minimum 6,357 km (3,950 mi) at either pole. A nominal Earth radius is sometimes used as a unit of measurement in astronomy
