A square is inscribed in the circle x^2+y^2-2x+4y-93=0 with its sides parallel to the coordinate axes. The coordinates of its vertices are (-6,-9),(-6,5),(8,-9),(8,5) (-6,-9),(-6,-5),(8,-9),(8,5) (-6,-9),(-6,5),(8,9),(8,5) (-6,-9),(-6,5),(8,-9),(8,-5)

NaCl is a AB type of solid . Its crystalline structure is known as rock salt structure in which r_"Na"^+ and r_"Cl"^- are 95 and 181 pm respectively , where Cl^- is present at the lattice point of face centered cubic unit cell Na^+ ions are located in void and those compounds which have same crystalline structure also have same coordination system in which Na^+ and Cl^- ions are surrounded by certain number of opposite ions respectively. Under high pressure coordination number changes to 8 :8 type from 6 :6 type. On Subjecting NaCl under high pressure it changes
