WebPi Day is celebrated on March 14th (3/14) around the world. Pi (Greek letter “ π ”) is the symbol used in mathematics to represent a constant — the ratio of the circumference of a circle to its diameter — which is approximately 3.14159. Pi Day is an annual opportunity for math enthusiasts to recite the infinite digits of Pi, talk to their friends about math, and eat … WebIf the line cuts through the circle, there will be two points of intersection; If the line is a tangent to the circle, there will be one point of intersection; If the line misses the circle, there will be no point of intersection; Example. The diagram below shows the circle \({x^2} + {y^2} + 18x + 20y + 81 = 0\) and three lines:
