Answer:

$\huge\pink{\bold{\tt{12,746 \:km}}}$

The diameter of a circle is twice the radius, giving us a diameter for Earth of 12,756 km.

Note: The Earth is almost, but not quite, a perfect sphere. Its equatorial radius is 6378 km, but its polar radius is 6357 km in other words, the Earth is slightly flattened.
