Budgiekk Posted October 31, 2009 Report Share Posted October 31, 2009 (pie r 2) multiply by the height ....30cm but i also guess its not symetrical?? equal width! Link to comment Share on other sites More sharing options...
reddevil6 Posted October 31, 2009 Author Report Share Posted October 31, 2009 sorry (pie r 2)?um na its round and 50cm what ever way i measure it Link to comment Share on other sites More sharing options...
bufo marinus Posted October 31, 2009 Report Share Posted October 31, 2009 At the risk of sounding like an old fart, you lot were supposed to learn this shit at school for fuck sake area = pi(3.14) x radius squared OR if the pot is square area = length x widtharea x height = cubic volume1000 cubic centimeters = 1 litre of water There, you have the information, I'm not working doing the sums for you as well, get off your arse and work it out yourself. You's can thank me by ensuring any children your responsible for in life don't turn out the same Link to comment Share on other sites More sharing options...
BaronS Posted October 31, 2009 Report Share Posted October 31, 2009 (edited) round pot, 50cm (diameter, 25cm R) and maybe a bit tapered, call it straight. 3.14159*25^2*30=58904.8125cm^3 litre? 10*10*10cm? 1000cm^3 58 litres? If you wanted to account for the taper you could use the average R for the depth, which is also the R at half depth if it has straight sides. EDIT: Sorry Bufo, did the sums while you were typing. Yep, should have left it alone :-) Edited October 31, 2009 by BaronS Link to comment Share on other sites More sharing options...
brick Posted October 31, 2009 Report Share Posted October 31, 2009 Or you could look at the bottom of the pot, sometimes they have the volume stamped on the bottom. 250mill = 8.1 ltrs And I agree with you buffo. Schooling is not quite the same anymore. Link to comment Share on other sites More sharing options...

Budgiekk Posted October 31, 2009 Report Share Posted October 31, 2009 sorry (pie r 2)?um na its round and 50cm what ever way i measure it pie r 2 is the area of a circle your 50 cm right?50 X 30 = 4710 4.71 litres basic geometry! Link to comment Share on other sites More sharing options...
BaronS Posted October 31, 2009 Report Share Posted October 31, 2009 what's an order of magnitude?I _spit_ on decimal places. :-) Link to comment Share on other sites More sharing options...
louise Posted November 6, 2009 Report Share Posted November 6, 2009 An order of magnitude is a scale used to make rough comparisons. Another way of determining the volume of a pot (without math) is to line the pot with a plastic bag and then fill pot with water from a measuring jug.
