That's the Earth's radius. It's about 6378 kilometers at the equator.
That's 3963 miles.
on the surfaceNote:Since the earth's composition is not homogeneous, the gravitational acceleration onthe surface is probably less than what it is some small distance below the surface,but it's certainly greater than at the center.

Infinity
The distance from the surface of the Earth to its center is approximately 6,371 kilometers.
The average distance from Earth's surface at the equator its center is about 6378 km. The distance from near the north and south poles to the center is somewhat less.
That would have to be at a radius that is sqrt(26) = 5.1 times the Earth's physical radius, or about 32,486 kilometers (20,186 miles) from the center.
The distance from surface to surface through the center of a planet would be that planet's "diameter".
The distance between the surface at the center of a reflective surface and its focal point is equal to half the radius of curvature of the surface.
Yes.

A curved surface on which all points are the same distance from the center is called a sphere.
You would have to double your distance from the center of the earth, or about 4,000 miles off the surface.
