document.write( "Thanks for your reply,<BR>\n" );
document.write( "I am sorry for the confusion in my previous queation.Actually, I am a Chemical Engineer and I am doing research in Ball Mill. Actually Ball mill is a Cylindrical mill used for grinding powders in Powder processing industries like cement, ceramic and paint.In this cylindrical mill,  balls are added for grinding powders. So I have to calculate Volume of mill occupied by balls. <BR>\n" );
document.write( "But the company people will give only ball bed height of the mill i.e. they are having a standard ROD and they will insert the rod into the mill and measure the ball bed height inside the mill. So with this given data I have to find out the Volume of mill occupied by balls.\r<BR>\n" );
document.write( "\n" );
document.write( "Here I assumed the part of mill occuying the balls as Segment area of Circle. So I wish to calculate the Area of this segment. So by multiplying this area with Length, I will easily get my desired result. i.e. Volume of mill occupied by balls. I HAVE TRIED WITH AREA OF SEGMENT FORMULA WHICH IS (AREA OF SECTOR - AREA OF TRIANGLE) AND IT CONTAINS AN INVERSE OF COSINE TERM. BUT I AM GETTING HIGHER VALUE(WHICH IS LARGER THAN MILL AREA).SO PLEASE HELP IN THE FORMULAE AVAILABLE FOR DETERMINING SEGMENT AREA OF CIRCLE. I NEED DIFFERENT FORMULAE OF THIS. PLEASE REPLY<BR>\n" );

document.write( "You have a cylinder which is hollow? and balls of cement (or whatever) are added to the mill?\r<BR>\n" );
document.write( "\n" );
document.write( "Now, is the cyclinder filled with balls, until no more can be fitted in?\r<BR>\n" );
document.write( "\n" );
document.write( "Assume each ball is the same but do not know the dimensions of it...then we will have to theorise on the volume of a ball by 4/3pi*r^3 and know how many it takes to fill the mill, then work out their total volume then calculate the mill volume, from its cross-sectional area times its length.\r<BR>\n" );
