Earth's radius is a little less than 4000 miles.
The equatorial radius of the earth is only 3963 miles while an AU is over 92 million miles. 3963 divided by 92,955,807 (an AU, approx) equals .0000426331622 AU.
3963 miles
This is the Earths radius. The Earth has a radius of 6371km on average. It is a slightly 'squashed sphere' though, due to its spin pushing out at the equator. Its polar radius is 6357km, while its radius at the equator is 6378km
Approximately 6 400 000 meters at the equator. However it is not a perfect sphere, it is rather 'squashed' at the poles, so the radius there will be less. This is the reason you weigh more as you move away from the equator.
3397 km at equator, 3375 km at pole
Mercury's radius is 0.3825 that of Earth Jupiter's radius is 11.209 that of Earth So: (0.3825/11.209)*100 = 3.41 percent.
the earth's equator
The radius of the earth is about 3,970 miles at the equator, a little bit less from the center to the poles.
The radius at the equator is 3,963 miles. It's slightly less through the poles.

circumference
Planet Earth has a radius of about 3,960 miles.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
It will increase very slightly at the poles compared to the equator, because the Earth's radius at the poles is slightly less than it is at the equator.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.
According to NASA, the earth's equatorial radius (not raduis) is 6378.1 km.
That's the Earth's radius. It's about 6378 kilometers at the equator. That's 3963 miles.

A pendulum will swing slowest when closest to the equator. Why is this? The time period, T, of the swing of a pendulum is given by: T=2π√(l/g) where l is the length of the pendulum and g is acceleration due to gravity. Because the Earth is spinning, there is a bulge at the equator and the poles are slightly flattened. Hence on the equator the radius to the centre of the earth is greater than the radius at the poles. The equatorial radius is 6378.1km while the polar radius is 6356.8 km The value of g at the Earth's surface relates to the values of the Earth's radius, r, at that point using an inverse square law ie g is proportional to 1/r2 At the North Pole, g is about 9.83m/s2, while at the equator, g is smaller, at only 9.79m/s2 . So the period of a pendulum will be longer (i.e. slowest) at the equator than at the pole
