I will explain in a few steps on how to find the circumference of a circle with radius 9.5mm.
To start off, remember that: 2 multiplied by pi multiplied by radius is how you find the circumference. In short form, 2*pi*r
pi is equal to 3.14.
We will now multiply 2 with 3.14 which is 6.28. 6.28 multiplied by 9.5 is equal to 59.66.
The circumference of the circle is 59.66 mm.
Hope it helps.
