Circle Notes - Harris County School District
–the distance around the outside of the circle –the measure of the inside of a circle (always measured in square units) Pi – the ratio of the Circumference to the diameter of the circle ----- d S S is the symbol for Pi Pi is approximately 3 14 because it takes a little more than 3 diameters to go around the Circumference of any circle

area of an object to the area of a circle with the same perimeter – A circle is used as it is the object with the most compact shape – The measure takes a maximum value of 1 for a circle – A square has compactness = 2 4 compactness area perimeter π⋅ = π4
DETERMINE THE AREA AND CIRCUMFERENCE OF A CIRCLE
x The area of a circle is the space contained with in the circumference It is measured in square units x The area of a circle is calculated by multiply pi ( ) times the radius squared : U How to determine the area and circumference of a circle: x Use the formula & x ' to calculate the circumference of a circle

Barlow formula (hoop stress): P = 2 x t x S ÷ D P = Working pressure in PSI with a 4:1 Design Factor t = Wall thickness, in inches S = Allowable stress (12,500 with a 4:1 Design Factor) D = Outside diameter, in inches D = √ A/ 7854 Atmosphere: Atmospheric pressure is 14 7 psi at sea level One Bar is equal to 14 5 psi (Atmos - 1 01 Bar)
Arctic circles, domino tilings and square Young tableaux
The arctic circle theorem of Jockusch, Propp, and Shor asserts that uniformly random domino tilings of an Aztec diamond of high order are frozen with asymptotically high probability outside the \arctic cir-cle" inscribed within the diamond A similar arctic circle phenomenon has been observed in the limiting behavior of random square Young
