Assuming that raduis is mean to be radius, the answer depends on what characteristic of what shape the 2m measures.
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 approx 60,268 km.
The radius (not raduis) is 6 inches.
The radius (not raduis) is 1.25 cm.
The radius (not raduis!) is 3.183 cm, approx.
There is no such word as raduis. The radius of 64 depends on what 64 is a measure of!
Radius (not raduis) =circumference/(2*pi)
Assuming the diameter is 10.8 then the radius (not raduis) is 5.4 units.
Potassium has the larger radius (not raduis!).
Calcium has a larger radius (not raduis) than copper.
If the diameter is 9 units then the radius (not raduis) is 4.5 units.
