Approximately 6400km.Diametre between poles is about 12713km.
The radius of the earth is 6400 km.The total surface area is 4*pi*radius square
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
The radius at the equator is 3,963 miles. It's slightly less through the poles.
Diameter- A line going straight from side to side of a circle, equals the total distance across the circle. Radius- Half of the total diameter. For example, if the diameter is 8, the radius is 4.
The equatorial radius 3,396.2 kilometers (2,110miles).The equatorial circumference of Mars is 21,339 kilometers (13,259 miles).Compared to Earth, the ratio is .533, i.e. the radius and circumference of Mars is about half the radius and circumference of Earth.
The radius of the earth is 6400 km.The total surface area is 4*pi*radius square
Venus has a radius of about 6,052 kilometers, which is about 95% of Earth's radius.
The Earth's crust represents about 1% of the Earth's radius. It is the thin outermost layer that ranges from about 6 to 43 miles (10 to 70 kilometers) thick. The Earth's total radius is around 3,959 miles (6,371 kilometers).
Venus has a radius of 6,051.8 kilometers, which is about 95% of Earth's radius. In terms of mass, Venus has about 81.5% of Earth's mass.
The Earth's radius is approximately 6,371 kilometers and 3,959 miles.
If you are a believer, then God did but if you are not, then nobody did. The radius of the earth existed and therefore ots radius did before there was any form of life on earth to invent it.
The radius of Earth is approximately 6,371 kilometers.
The Earth's crust is relatively thin compared to the overall size of the Earth. It is estimated to be between 5-70 kilometers thick, whereas the Earth's radius is about 6,371 kilometers. This means the crust only accounts for a small fraction of the Earth's total radius.
Mercury's radius is about 38% of Jupiter's radius.
The radius of Earth is about 0.95 times greater than the radius of Venus.
Europa: 1561 km radius Earth: 6371 km radius The diameter is twice the radius.
Earth's radius is about 6,371 km, so Earth's radius is approximately 1.88 times larger than Mars.
