15mm what? Diameter or radius? Formula for finding Circumference is Pi X Diameter. If 15mm is the Diameter, multiply 15mm by 3,1614 = 47.124mm. If 15mm is Radius, then multiply Radius by 2 to get Diameter and then multiply by 3.1416 = 15 X 2 = 30 X 3.1416 = 94.248mm.

If you know the circumference of a circle, you can find the radius by dividing the circumference by the value of Pi (3.14159...)
Diameter of a circle = circumference/pi
to find the circumference of any circle, times the diameter(d) by pi and you will get the answers.
In a circle, the circumference and diameter vary directly. Which of the following equations would allow you to find the diameter of a circle with a circumference of 154 if you know that in a second circle the diameter is 14 when the circumference is 44?
Remember the circle eq'ns. C = 2 pi r or C = pi d (A = pi r^(2) ) pi is the circular constant of value 3.141592.... Reduced to pi ~ 3.14 ( For learning purposes). Hence C = 3.14 d Algebraically rearrange the eq;n. d = C/3.14 Substitute in C = 47.1 cm d = 47.1 cm / 3,14 d = 15 cm
