If you mean formula for vircles. It is EQUATION .
Circumference equals 'pi' multiplied to the diameter , or
Circumference equalls 'pi' multiplied to '2' and the radius.
C = pi*d
C = 2pir
The '*' means multiply.
pi ~ 3.14 or ~ 3.1416 or ~ 22/7

What is the formula for finding the circumference with radius?
the circumference is two times the radius, or 2r. so if the radius was 3, the circumference would be 6. if the radius was 4, the circumference is 8.
