4 is a number. It does not have a centre, not a radius.
I think it is center: (-4, 3) ; radius: 2 Apex:)
center 5,-3 radius 4

4 units The radius of a circle is the distance from the center to the edge. The diameter of a circle is the distance from the edge, going through the center, to the opposite edge.
x² + y² = 4.

The formula for the surface area of an elbow (or 90° angle) is (pi^2 * (radius2^2 - radius1^2) ) / 4. Where pi = 3.14159, radius 2 = the radius from the center to the outside, and radius 1 = the radius from the center to the inside.
4 units The radius of a circle is the distance from the center to the edge. The diameter of a circle is the distance from the edge, going through the center, to the opposite edge.
x² + y² = 4.
This makes no sence
If you have a cylinder with a radius of 4 inches and a height of 4 inches, its dimensions describe a shape that is 4 inches wide and 4 inches tall. The radius is the distance from the center of the base to its edge, while the height is the distance between the two bases. Therefore, the cylinder's radius is 4 inches and its height is also 4 inches.
It is x2 + y2 = 4
circle has single center point and is equidistant to point of radius,while oval has four(4) center points with two(2) different radius.
The radius is the line from the center of a circle to its circumference.
It is (x - 7)^2 + (y - 4)^2 = 4
