They gave me the value of r and asked me for the value of C‚ so I’ll just "plug-n-chug": C = 2(pi)(3) = 6pi Then‚ after re-checking the original exercise for the required units (so my answer will be complete): the circumference is 6pi cm. Note: Unless you are told to use one of the approximations for pi‚ or are told to round to some number

equal to 12345678 9 87654321 You can remember the value of PI (3.1415926) by counting each word’s letters in “May I have a large container of coffee?” 21978 when multiplied by 4 is the same number with digits in reverse order... 21978 x 4 = 87912 If you add up numbers 1-1000 consecutively (1+2+3+4+5…) the total is 5050. From 0 to 1000‚ the letter “A” only appears in 1000 (“one thousand”). The billionth digit/number of Pi is 9. The digits to the right of the Pi’s (3.141…) decimal

History Mathematicians have known about pi for thousands of years because they have been working with circles for the same amount of time. Civilizations as old as the Babylonians have been able to approximate pi to many digits‚ such as the fraction 25/8 and 256/81. Most historians believe that ancient Egyptians had no concept of π and that the correspondence is a coincidence.[4] The first written reference to it dates to 1900 BC.[5] Around 1650 BC the Egyptian Ahmes gave a value in the Rhind Papyrus

sphere of radius R inside a cylinder‚ with the cylinder just touching the equator‚ and cut off at the height of the top and bottom of the sphere. (A cutaway view is in the diagram.) [pic] What is the area of the curved part of the cylinder? 2 Pi R x 2R = 4 Pi R2. This is found by slicing the cylinder surface and rolling it out as a rectangle. Now‚ it is NOT an accident that the cylinder surface is EXACTLY the area of the sphere. Take in small horizontal slice through the diagram. (I have colored

working only three days a week for long hours or working five days a week with a shorter hours which is much more enjoyable for employee. As for me‚ working five days a week for shorter hours is more convenient for its regularity‚ consistence and unnecessariness. First‚ a regular life style is the mainly point I care about. Choosing to work three days a week means that we have to sleep late in night during the work day because of the lengthened work hours. However‚ in the other four days‚ on the contrary

[edit] Mathematics [edit] Pi as irrational Aryabhata worked on the approximation for Pi (π)‚ and may have come to the conclusion that π is irrational. In the second part of the Aryabhatiyam (gaṇitapāda 10)‚ he writes: caturadhikam śatamaṣṭaguṇam dvāṣaṣṭistathā sahasrāṇām ayutadvayaviṣkambhasyāsanno vṛttapariṇāhaḥ.
