Yes If your circle is 50cm accross then your radius is 25cm. You do 25*2=50 then 50*3.14 which is 157.07963267948966 cm
I'm sooooooo out of 1.4.2! I mean like a day after 1.3 came out everyone was like I can't wait until 1.4 comes out!! So I'm like really ANOTHER update like a month apart?? Jeez Laweez! I can't belive this! They add like 100 MORE items in a month or 2!! Is that crazy or what??
As far as pi goes, go watch the movie Contact, which turns out is something else you can do while waiting...
