For a circle, the perimeter is called the Circumference and is given by the equation-:
2 x pi x radius
or
pi x diameter

The perimeter of a circle is known as the circumference of the circle.
Let C be the circumference:-
C = ÏD where D is the diameter and Ï = 22/7 = 3.14
C = 2ÏR where R is the radius.

Perimeter of a circle = 2*(pie)*r where pie = 22/7 and r is the radius of the circle.

Yes to all of the above.
It is also the locus of points equidistant from a single point called the 'center' and the distance to them from the center is called the 'radius' of the circle. If a circle of radius r is located such that its center is at the coordinates (h,k) then the equation defining it is
(x-h)² + (y-k)² = r²

It is called the circumference. It is equal to 2 * Pi * r where r is the radius
