It is the numerical value of the radius - usually of a circular shape - multiplied by itself. It has no particular significance in itself and is a proportion of the surface area of the object. What proportion of the area depends on whether the object is a circle or sphere.
That is the same as radius x radius.

How do find the area of a circle?
Pi x radius(R) squared e.g radius of circle is 5cm A=3.14x5 squared Area is 78.5
What is a radius square?
When you try to figure out an area of a circle, you square the radius, then multiply it by pi to get the area of a circle. A radius square is radius x radius, or radius squared.
In the formula for the area of a circle what gets multiplied by 3.14?
The radius squared. The radius is half of the diameter
How do you find the diameter if you have the area of a circle?
Since the area of a circle is (Pi)times(Radius squared) then you would reverse the process to find the radius, and hence, the diameter. Divide the area by Pi (3.14159...) and you would have the radius squared. Take the square root of that and you have the radius. To get the diameter, multiply the radius by 2.
What is the formula to find the area of a circle with the radius given?
A = pi x radius squared where pi = 3.14
