Kieran Morrison Posted January 27, 2011 Report Share Posted January 27, 2011 (edited) Hey, most of you will probably find this quite easy, but to me its hard. Got this homework today and I cant figure it out Cant post a pic so illtry and describe it. There is a square of 800m in length. The square is filled with circles 100m diameter. I need to find the area of the Space inbetween 2 circles. So any help? Cheers Edited January 27, 2011 by Kieran Morrison Quote Link to comment Share on other sites More sharing options...
PeanuckleJive Posted January 27, 2011 Report Share Posted January 27, 2011 (edited) Are the circles laid out in rows of 8, or is space conserved by having a row of 8, then a row of 7 laid in the gaps, then a row of 8, row of 7, etc....? P.S. Area of a circle = Pi R squared R is Radius, which is half of the diameter. everything you need is there, Do the maths yourself Kieran, that's why you're at school Edited January 27, 2011 by PeanuckleJive 1 Quote Link to comment Share on other sites More sharing options...
Matthew62 Posted January 27, 2011 Report Share Posted January 27, 2011 Well if the circles are next to each other there is no space so i'm guessing this is not the solution....in that respect without telling us how many circles there are we can't answer your question.

trials owns Posted January 27, 2011 Report Share Posted January 27, 2011 find area of one circle, time that by how many there are, keep that number. find area of square then with that number take the area of all the circles away. think that how it goes anyho.

PeanuckleJive Posted January 27, 2011 Report Share Posted January 27, 2011 I'd say that's more than enough info now, Now let's find an equation for working out how long it takes the bandwagon to come along and flame Kieran as usually happens Quote Link to comment Share on other sites More sharing options...

Correct. Tis easy Good way of you doing it is to draw a square, then lay out the circles in the square 8x8. May find it easier.

Think I've got it, cheers 'trials owns' Yeah im not gonna wait to be flamed lol topic can be closed. Quote Link to comment Share on other sites More sharing options...
