The circumference is 25.1
In order to fully understand what the radius of a given circle is, you must know the diameter. The diameter is the distance across the circle through the center. The radius of a circle is half the diameter. For example, if the diameter of a circle is 8 inches, then the radius would be 4 inches.
A=pi x radius squared Example: circle with a radius of 2 would be worked out like this: 2 squared (4) x 3.14. Answer= 12.56
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

Since you said radius, I assume you mean Circle or Sphere. Circle: Area = Pi * radius^2 therefore, Radius = Square Root of (Area/Pi). Sphere: Area = 4/3 Pi * Radius^3 therefore, Radius = CubeRoot of (3/4 * Area/Pi)
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.
Given: Radius, r=4 Area, A=(22/7)*r*r A=(22/7)*4*4 A=50.2857 sq. 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.
