Solving for circumference of a circle
Web5 years ago. You just need to use the equation. First, find the equation for the circle. Like this, x^2 + (y - 3)^2 = 9. Then, input the x and y values into the equation. If it's bigger than 9, the point is outside of the circle, if it's equal to 9, the point is on the circle, and if it's smaller than 9, the point is inside of the circle. 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.
