∙ 14y agoThe 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
The radius of curvature is given by(1)where is the curvature. At a given point on a curve, is the radius of the osculating circle. The symbol is sometimes used instead of to denote the radius of curvature (e.g., Lawrence 1972, p. 4).Let and be given parametrically by(2) (3)then(4)where and . Similarly, if the curve is written in the form , then the radius of curvature is given by
8 units; the diameter of a circle is twice its radius.
