Well, honey, "radii" is the plural form of "radius." So, if you're talking about one of those lines from the center of a circle to any point on its circumference, that's a radius. But if you're feeling fancy and need to talk about more than one, then you're dealing with radii. It's as simple as that, darling.
In geometry, a radius is a line segment that connects the center of a circle to any point on its circumference. The plural form of radius is radii, which refers to more than one radius within the same circle or sphere. So, the main difference between radii and radius is that radii is the plural form of radius, indicating multiple line segments from the center to the circumference of a circle.
The noun radii is already a plural. The singular is radius.

It is radii which is the plural of radius
Classically, the plural should be radii, (usually pronounced ray-dee-eye) because 'radius' is a Latin word.However, in modern English, radiuses is acceptable.
The formula for the circumference, (C) of a circle is C = 2πr.....where r is the radius. Let R be the radius of the larger circle and r the radius of the smaller circle. Then 66 = 2πR - 2πr = 2π(R - r) Then R - r = 66/2π = 33/π ≅ 10.504 The difference between the two radii is 10.504 (3dp)
The plural of radius is radii.
