The concept to be used in order to determine the diameter of the second cell in the photograph is that of the ratio and proportion. The ratio of the first set of measurements should be proportional (equal) to the ratio of the second set.
Ratio of first set of diameters,
r = diameter of Cell A / diameter of Cell B
r = 12 micrometers/20 micrometers
r = 3/5
If we let D be the diameter of the cell B in photographs,
r = 3/5 = 15 cm/x cm
The value of x from the equation is 25. Hence, the diameter of cell B is 25 cm.
Carbon (from Latin: carbo "coal") is a chemical element with the symbol C and atomic number 6. It is nonmetallic and tetravalent—making four electrons available to form covalent chemical bonds. It belongs to group 14 of the periodic table.
