'pi' is an IRRATIONAL number. This means that its decimal digits go to infinity and the digits are not in any regulr order. Super Duper Computers have calculated 'pi' to more than 50 billion places, and stil going. However, for school work , pi is 3.14, 3.1416, 22/7 These are only approximate values. 'pi' has been known from pre-Classical history . It was found that the circulaference of a circle was always directly proportional to its diameter. The Constant of PROPORTION is 'pi'. 'pi' is the Classical Greek samll /lower case letter 'p' and stands for propotion. The circle equations you should learn in school are ;- C = pi d ( circumference and diamter) C = 2 pi r (circumference and radius) A = pi r^(2). ( Area and radius squared).
It depends on what the school prefers. I would think that 9th graders in a school for kids with learning disabilities normally learn Pre-Algebra, or Algebra 1. For a 9th grade class in a mainstream school, I would think that most 9th graders would learn Algebra 1, Geometry, Algebra 2, or Trigonometry. I would think that Trigonometry is mostly for gifted 9th graders.
An INFINITE number. Computers have calculated 'pi' to billions of places and still going. However for everyday school learning pi = 3.14 or pi = 22/7 . For more accurate calculations pi = 3.1416 . This is used in science, technology and engineering.
the area of a circle is represented by the following equation; A=pi*R2 where A is area, pi is the number pi (3.1415926.......for most high school maths, 3.14 is suitable) and R is the radius. So, square your radius, and multiply it by pi.
Circumference = pi times diameter or Circumference= two x pi x radius. Now remember the diameter of a circle is the straight line from one edge of the circle, through the centre to the opposite edge. The straight line from the edge to the centre is the radius, and then from the centre to the opposite edge is another radius. So the diameter is the length of two radii. Algebraically express as d = 2r. So Algebraically C = pi*d Substituting the 'd' for '2r' C = pi2r However in algebra coefficient numbers are expressed to the left. Hence C = 2pir Why 'C' is this expression I would have to go into some 'very heavy' differential calculus. Suffice it to say, the ancients found that the circumference traced by a donkey/mule driving water out of well was directly proportional to the diameter, twice the length of the tether(2 radii). From this they discovered that for however long the the tether and the circumference were. they had a constant of proportion C directly related to diameter. This is equated to C = kd And k = C/d , which was founf to be 3.141592..... which now call 'pi'. for any sized circle. So today in school you learn C = pi d or C = 2 pi r And for circular area(A) A = pi r^(2) The 'pi' youare given in school is proabably 3.14 , 3.1416 or 22/7 . However, these values are Approximatons, because 'pi' is an irrational number. Hope that helps!!!!!!
You will typically learn about Greek Mythology in an English class at school. You will also learn about Shakespearean works.
You can learn it at school in typing or keyboarding class, or you can learn on your own by taking a class on the internet or buying an instruction book. It's just a matter of practice.
You learn the language, or you can go to school and take a class where they learn how to speak french for beginners.
Learn how to speak French....
Well, you can learn how to act, be creative, have many class shows or even perform in a play for the school.
Taking a class such as learning how to create an iPhone app cannot and will not count as a high school credit. Since it is not a course available to everyone, and since it isn't approved by the school district you are in, you cannot make it count as high school credit. This must be something you must learn on your own.
you are in school to learn whatever is being taught. focus on the teacher & socialize after class.
take a civil rights class in high school or take an advanced class in college
yes . I think it is better to have that method
Pay attention in class. That is the simplest way.
"what school and which class"
There are many tutorials online to learn about video editing. Another great source of information would be a class at a local school.
