Square the radius and multiply the result by 3.14. You may want additional digits of pi for greater precision, but that's the basic idea.
The formula is πr² (that's "pi r squared," if the character doesn't show up properly).
ANSWER:The above answer is wrong! The above gives the area of a circle, not the circumference. Besides pie are round, cornbread are square.Pi = 3.1416 as stated above.
The circumference of a circle is 2 times the radius times pi .
This is because pi for all circles is the circumference divided by the diameter. So, pi times the diameter equals the circumference. The diameter is twice the radius.
