Best Answer

The circumference of any circle divided by its diameter is always equal to pi which is about 3.142 rounded to 3 decimal places.

The exact true value of pi is not known because the decimal places of pi are infinite.

To calculate properties of circles

Usually a circle but its properties can also be applied to spheres

They have a circumference which is 2*pi*radius or diameter*pi They have an area which is pi*radius2 They have sectors They have chords They have segments They have a total of 360 degrees around their circumferences They have arcs which is part of their circumferences They can have a tangent which is a straight line that touches it at one point

A ball with that many faces would be close to a sphere, so its volume ans surface area, and other properties could be approximated using pi.

They are measures of angular displacement. In two dimensional space they may be measured in degrees (by beginners) or in radians. There are 2*pi radians in a revolution. In 3-d space angles are measured in steradians. A sphere measures 4*pi steradians

Many properties. For example, 1 + 1/1! + 1/2! + 1/3! + 1/4! + ... = e. This is not true for pi.

The simple answer is that PI is what falls out when you study circles. If I had a circle that is 1 foot in diameter, then the circumference (or perimeter) is PI feet. The numerical value of PI wasn't chosen at random, it was found. As for the area of a circle, the perimeter of any object has a relationship to its area. So, PI again becomes important.

The constant "pi" 0,314159...... is used in every branch of science, from calculating material quantity for domes in construction to calculating absorption properties of new substances in chemistry. To calculate the circumference of a circle = c = 2(pi)r The area of a circle a = (pi)r² you can also use the formula (pi)d to find the circumference Although pi has solved countless problems, no problem has ever been solved with whatever pi equals EXACTLY. Therefore, when using pi to solve a problem, the majority of mathematicians and scientists round pi down to 3.14

How to find the final digit of the symbol pi which is used in finding the properties of circles and spheres

Conjugated pi electrons are electrons that are delocalized over multiple atoms in a molecule due to the alternating single and double bonds in a conjugated system. This delocalization allows for enhanced stability and unique electronic properties in conjugated systems, such as extended pi bonding and increased reactivity.

A delocalized pi bond is commonly found in conjugated systems such as benzene rings or in molecules with alternating single and double bonds like in polyenes. This delocalization leads to increased stability and unique chemical properties.

Knowing the area of a circle which is pi times radius squared will help you to find other properties of the circle
