The area of a circle with radius is given by the formula A=pie times radius to the 2nd power
make an table of values for A as r (radius) increases from 0 to 10 unit
r A
______
0 0
1 pi*1
2 pi*4
3 pi*9
etc.Note the correct spelling of pi.
isn't that impossible to do it on a graph cuz u are multipling by itself so 10 times 10= 100
The question was to make a table. I made a table for you to use using zero, 1, 2, and 3. You simply continue using 4, 5, 6, 7, 8, 9, and 10. And 10 x 10 will be 100, when you get to that number, but, again, the question was to make a table. You didn't say anything about a graph. However, IF you are to plot a graph, too, you just make the scale of the graph so that 100 will fit on it and draw the graph from the table. I hope this helps.
thanks
I need to no / salt is made up of two elements sodium and chlorine imagine if you could divide a crystle of salt over and over again what will happen when you finally divide a single molecule of salt?
When you have divided it molecule by molecule until there is only one molecule of NaCl left, that is the smallest particle of NaCl you can have. If you divide it any more you will not have NaCl; you will separate the ions and you will have ATOMS of sodium and atoms of Chlorine.
When you divide a crystal of salt over and over again, you eventually reach the smallest particle of salt, which is a single molecule of sodium chloride (NaCl). Each NaCl molecule is made up of one sodium (Na) atom and one chlorine (Cl) atom, bonded together. These atoms are held together by ionic bonds, which are strong electrostatic attractions between positively-charged sodium ions (Na+) and negatively-charged chloride ions (Cl-).
If you continue to divide a single molecule of salt, you would break the ionic bond between the sodium and chloride ions. This would result in separate sodium atoms and chloride atoms, rather than a molecule of NaCl. This is because, in their elemental states, sodium exists as single atoms (Na) and chlorine exists as diatomic molecules (Cl2), where two chlorine atoms are bonded together.
So, dividing a single molecule of salt further would not give you smaller particles of salt, but instead, you would end up with individual atoms of sodium and chlorine.
