cgksheff Posted August 22, 2005 Share Posted August 22, 2005 You're out by a factor of 2. Circumference is calculated using Pi x Diameter. The increase in circumference is equal to Pi x the increase in diameter. 6 inches is the increase in radius. So the increase in diameter is 2 x 6 = 12. So the increase in circumference is 2 x 6 x pi = 37.7 inches. Link to comment Share on other sites More sharing options...
Phanerothyme Posted August 22, 2005 Author Share Posted August 22, 2005 Hmm, I got this right last time, how come my answer is 19 billion inches? anyway now try this one "there is one A in this sentence, one B, two Cs, one D, thirteen Es, one F, one G....." see how far you get!

In the last weighing, either 1 will be heavier, or both will be the same, in which case the one you didn't weigh in the last lot will be the odd one out. Originally posted by Phanerothyme ...You have a nice long piece of string that neatly fits exactly around the world at the equator. Let's assume the earth is actually flat as a billiard ball... If the world was flat would it have an equator? Here's one for you all... You're driving along the road in your 2 seater. At a bus stop you see three people... The first is an old friend who once literally saved your life... The second is a very frail looking old person who could obviously do with getting to the hospital like now... The third is the male/female/mammal of your dreams (assume you're single)... Obviously the car will only fit 2 people, & as soon as you leave the area you won't see any of them again. What do you do?

Cyclone Posted August 22, 2005 Share Posted August 22, 2005 give the car to your old friend (along with your mobile number). Ask him to drive the old person to the hospital. Catch the bus with the hotty. Link to comment Share on other sites More sharing options...

Cyclone Posted August 22, 2005 Share Posted August 22, 2005 Originally posted by steev Full marks that dude!! Have you seen that before, or are you really that quick?!? not seen it before, just seemed obvious. I'm pretty good on logic generally. Not sure if giving your mobile number out is cheating though. Otherwise you could give it to the hotty as well, and call an ambulance for the old guy, leaving you free to carry on driving around. Link to comment Share on other sites More sharing options...

Meh, well the actual answer was to get your friend to drive the frail person to the hospital, & wait at the bus stop with aforementioned "hotty" for him/her to come back with your car. The mobile number addition is just being clever Link to comment Share on other sites More sharing options...

You have to tell me which one is the odd one out, and whether it is heavier or lighter.... Flat as a billiard ball, obviously, means as smooth as. Billiard balls aren't flat either.
