The question, as stated, does not make sense.
The radius (not raduis) of curvature of a curve at a point is the radius of the arc of a circle which approximates the curve in the immediate vicinity of the point.
The length of a radius (not raduis) is diameter/2.
The radius (not raduis) is approx 60,268 km.
No, it cannot be a raduis. It cannot be a radius, either.
The radius (not raduis) is 1.25 cm.
The radius (not raduis) is 6 inches.
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)
If the diameter is 9 units then the radius (not raduis) is 4.5 units.
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.
