radius
If you mean the circumference or "perimeter": C = 2(pi)r, where r is the radius of the circle
that symbol means trademark
The circumference of a circle is its perimeter, or the distance around it. It equals 2(pi)r or pi*d, where r is the radius, d is the diameter and pi is 3.14...
The circumference of a circle is the distance all around the edge of the circle. To find the circumference of a circle, you use the formula C equals 2 times pi times r, where pi is equal to 22 over 7 and r is the radius.

The amount of space a circle takes up is determined by its area, which can be calculated using the formula A = π * r^2, where r is the radius of the circle.

The size of something, distance all around it.Circumference is the distance around the perimeter of a circle.
The area of the circle becomes 9 times the area of the original circle. Original circle = Pi * (r ^ 2) = Pi * r * r New Circle = Pi * ((3 * r) ^ 2) = Pi * 9 * r * r
