WebIf you know the diameter or radius of a circle, you can work out the circumference. To begin with, remember that pi is an irrational number written with the symbol π. π is roughly equal to 3.14. The formula for working out the circumference of a circle is: Circumference of circle = π x Diameter of circle. This is typically written as C = πd. WebSep 30, 2010 · circumference = 2 * 3.1416 * radius; (since 3.1416 is of type double, the type of rhs is double). area = 3.1416 * radius * radius; (same here) So, you lose precison. Don't do it unless it is intentional. Compile with the strictest warning level though that is not guaranteed to bring out all lurking issues.

WebSo the circumference is equal to 2 pi r. Circumference is equal to 2 pi r. And in this case, r is equal to 6. So it's equal to 2 pi times 6, which is going to be equal to 12pi. So that's straightforward, area 36pi, we leverage pi r squared to figure out that the radius was 6, and then from that we were able to figure out that the circumference ...
