You can completely specify a circle in a plane by giving the coordinates of its center point, and the length of the radius.
Just like any other circle, the area of that one is (pi) times (the square of the radius).
The radius of a circle is from the middle to the edge, or half the diameter. The circumference is like the perimeter of the circle, and the formula is pi times the diameter.
Basically a circle has a constant radius throughout and an ellipse does not.a circle has a constant radiusan ellipse has two foci. they are at either end of the ellipse
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

12 x 12 sounds like a square, not like a circle. To specify a circle, you need a single number, for example the radius or the diameter. Assuming the diameter is 12, the radius would be half of that (6 units). The "size" of the circle can be considered this radius (6), the diameter (12), or the area calculated by the formula pi * radius * radius.

A circle with a radius equal to the base of the cone. This circle will be tangential to a segment of a circle whose arc is the same length as the circle, and whose radius is the slant height of the cone.

I'm unable to show pictures. But a radius in a circle is a line segment that connects the center of the circle to any point on the circle's circumference. It is half the length of the diameter of the circle.
take your online summer school class like everybody else. stop trying to cheat you will never learn the material.
it looks like a circle.
A congruent figure is identical to another figure. Example would be like a circle with the radius of 12 meters, then the congruent figure would have to be a circle with a 12 meter radius.
all the points in the inscribed circle are also in the bigger circle. If all the points in the outside circle are the set O ... and all the points in the inner circle are the set I... Then I is a subset of O, just like a venn diagram
