[quote=lordpentt]pi r squared times 1000 or 2pi r, i cant remember which one is SA and which one is circumfrence X.X

btw TS, are u gay?

"I LOVE YOU"

just a random question O_O[/quote]

I'm not... And even if I were, it's none of your business lol

i said " i love you" because i couldn't figure the answer out by myself

[quote=hyperfire7]Um...you got the units wrong, and even if the unit was correct (cm, not km), the number is still either way too big (282,743,339cm), or way too small (2.82743339km or 2,827.43339cm). (I'm not sure if the comma u placed after the '2' is supposed to be a decimal or not).

OT: Circumference of a Circle is (Pi)(Diameter).
(Pi)(90cm) = 90Pi or about 282.74cm.
Now since we are measuring the distance after it spun 1,000 times, just simply multiply the Circumference by 1,000.
90Pi X 1,000 = 90,000 Pi or 282,742.33 cm.[/quote]
Thanks alot to both of you!

[quote=WerewolfKiss]The circumerence of a cirlce is 2*pi*radius or pi*diameter
So 1 rotations = pi*90 cm
1000 revs = pi* 90000 cm = pi * 900m = 2,82743339km[/quote]

I LOVE YOU!

I always sucked at Geometry....
