Webpi, in mathematics, the ratio of the circumference of a circle to its diameter. The symbol π was devised by British mathematician William Jones in 1706 to represent the ratio and was later popularized by Swiss mathematician Leonhard Euler.

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. Webπ.
