Compute Value Of Phi • From those equation we have – So, ratio of areas proportional to 𝜋 – How to find areas ? • Suppose we throw dart randomly at dartboard • Count total dart that landing inside the circle and total that landing on the square (total all darts) • Ratio of those numbers give approximation to ratio of area • Quality of approximation increases with number of darts
