Yes, providing that they stem from the center of the circle to its circumference.
You can have as many radii as you want. ANY segment that joins the center of the circle with any point on the circumference is a radius.
In order to even discuss this question, we must assume that the unit of the '40' is the square of the unit of the '4'. -- The radius, diameter, and circumference of the circle with an area of 40 are each 10.794% shorter than the corresponding measurement in the circle with radius = 4 . -- Its area (40) is 20.423% less than the area of the circle with the radius of 4 .
A circle has only one measure for its radius. A shape that has a "radius" of 3 in by 4 in cannot be a circle.

The radius of the circle is 2 units. * * * * * If the area is 4 units, the radius is 1.128 units
The area of a circle with a radius of 4 is: 50.27 square units.
Radius of a circle with diameter 4? Radius is half of the diameter, so in this case it would be 2.
The circumference of a circle with a radius of four is: 25.13
8 units; the diameter of a circle is twice its radius.
The area of a circle with a radius of 4 units is: 50.27 square units.
The circumference of a circle if the radius is 4 is about 25.13 units. (C = r x 2 x Pi)
its 4..... the radius of a circle is half of the diameter
4 cm radius = Area of 50.26548 sq. cm.
