What is the radius of earth?

Answer 1

Earth's Circumference at the Equator: 24,901.55 miles (40,075.16 km)

Earth's Circumference Between the North and South Poles: 24,859.82 miles (40,008 km)

Earth's Diameter at the Equator: 7,926.28 miles (12,756.1 km)

Earth's Diameter at the Poles: 7,899.80 miles (12,713.5 km)

Average Distance from the Earth to the Sun: 93,020,000 miles (149,669,180 km)

Average Distance from the Earth to the Moon: 238,857 miles (384,403.1 km)

Radius of Earth = 6 378.1 kilometers or about3961.3 miles.

Radius of the Earth is about: 3440.07 Nautical miles(nm)
The radius (the distance from the surface to the middle) of the Earth is 6, 378.1 km.
About 6400 kilometers.
The Earth's radius is approximately 6,376,136 metres along the equator and approximately 6,376,115 metres along the Prime Meridian.
Earth has 3 different radiuses. The mean radius is 6,371 kilometers. The equatorial radius is 6,378.1 kilometers. The polar radius is 6,356.8 kilometers
The radius of the earth is approximately 6378.1km
6,371 km

Answer 2

The average radius of the Earth is about 3,959 miles (6,371 kilometers). This value represents the distance from the Earth's center to its surface at the equator.

Answer 3

The approximate radius of the Earth's center to it's surface is about 6,371 kilometers, which is about 3.959 miles.
