WebFirst of all, let us assume that pi is a rational number, which means that it can be expressed as a/b, where a and b are integers with no common factors. We can also assume that this fraction is in the lowest terms, i.e. a and b have no common factors other than 1. Therefore, we have: pi = a/b. Multiplying both sides by b, we get: pi*b = a …(1) WebPhi for “Neo-Phi-tes:” Phi ( Φ = 1.618033988749895… ), most often pronounced fi like “fly,” is simply an irrational number like pi ( p = 3.14159265358979… ), but one with many unusual mathematical properties. Unlike pi, which is a transcendental number, phi is the solution to a quadratic equation. Phi is the basis for the Golden Ratio, Section or Mean The ratio, or …

WebThe perimeter of the polygon is P = n a, while the area of the polygon is A = n T = n a d 4. Hence, we get that A = P d 4 Letting the number of sides n tend to infinity, the polygon "tends" to a circle and we get that Area of the circle = Circumference × diameter 4 or to put it the other way around Circumference = 4 × Area of the circle diameter WebMar 29, 2011 · Answer: First divide the circumference by Pi to give the diameter of the circle (27 divided by 3.14 = 8.59...). Now halve the diameter to give the radius (8.59 divided by 2 is 4.29...). Now use Pi*r^2 to find the … how to screen capture gameplay
