Look what I've found about circles in real world:

Something that puzzles me is how crop circles are made.]]> 2018-03-28 03:29:35 UTC https://padlet.com/annysee/737bz6onoz7h/wish/246753150 the inventor https://padlet.com/annysee/737bz6onoz7h/wish/247175406 William Jones invented pi]]> 2018-03-29 08:54:39 UTC https://padlet.com/annysee/737bz6onoz7h/wish/247175406 phenomenon in China https://padlet.com/annysee/737bz6onoz7h/wish/247489846 Happening daily:
http://www.chinadaily.com.cn/a/201801/03/WS5a4c142ba31008cf16da4b7e.html]]> 2018-03-30 13:44:28 UTC https://padlet.com/annysee/737bz6onoz7h/wish/247489846 6 Integrity & Ms See: What is pi? https://padlet.com/annysee/737bz6onoz7h/wish/247667505 Many of us had the above wondering and some of our classmates mentioned that pi = 22/7 and 3.14. Thus, as a class, we set out to investigate about pi and also find out if what our friends said was true and what made them true. Ms See got us to measure real-life objects with circular surfaces to determine their respective circumference and diameter. From there, we went to find out if there is a relationship between the two.

We found the following: 

When we divided the circumference of a circle by its diameter, most of us got the answer of about 3.14.

Some of us obtained a value of more than 3.14 and Nifaal suggested that there is a need to measure the circumference of the circle and its diameter a few more times to increase the accuracy of our results. We could have made some errors while taking the measurements. (Hmmm... What do we think could have resulted in the errors?)

Ms See also got us to predict whether the circumference of the circular surface or the height of the cylindrical object would have a larger value and she got us to measure the height of our object too. For the Poppadom chips container, we were rather surprised that the circumference had a larger value even though the container was very tall! This was verified by Enrique who did not believe what Yu Xuan had shared and Jerlyn then remarked that we should not judge a book by its cover. How true indeed!
