Apart from the fact that there is no such thing as a raduis, the radius of 9 km depends on what the 9 km measures: the diameter, the circumference or something else.
The radius (not raduis) is approx 60,268 km.
1,134 km
According to NASA, the earth's equatorial radius (not raduis) is 6378.1 km.
If the diameter is 9 units then the radius (not raduis) is 4.5 units.
The radius of Earth is 6,378.1 kilometers, or 3,959 miles. The radius is the distance from the Earth's center to its surface.
circumference = 2*pi*9 inches

The length of a radius (not raduis) is diameter/2.
No, it cannot be a raduis. It cannot be a radius, either.
The radius (not raduis) is 6 inches.
The radius (not raduis) is 1.25 cm.
The radius (not raduis!) is 3.183 cm, approx.
