Calculating the Circumference of a Circle
The circumference of a circle is the distance around the outside of the circle. It could be called the perimeter of the circle.
How to find the circumference of a circle:
The circumference of a circle can be found by multiplying pi ¶ (which is equal to 3.14) by the diameter of the circle.
If a circle has a diameter of 4, its circumference is 3.14*4=12.56
If you know the radius, the diameter is twice as large.

circumference is 2 multiplied by radius and pie thus in your case it will be 2 multiplied by 50mm and 3.14 this equals to 314mm i.e. the circumference is 314mm

314.00. Radius is only half the diameter, so double that. Then with 100mm multiply it by 3.14. And you get 314.00mm. Your welcome.

Do you mean lemon pie or strawberry pie?
I like them both and they're in circular pie tins.
