Cell A Cell B
The student used the internet to research the actual diameter of these two types
of cell.
The student found several values for the diameters of cell A and cell B. They used the
mean value for the diameter of cell B to calculate the magnification of the drawing
of cell B.
The student calculated the magnification of the drawing of cell B to be × 1571.
The student found the following values for the diameter of cell A:
0.016 mm, 0.022 mm, 0.019 mm, 0.021 mm, 0.017 mm.
(a) Calculate the magnification of the drawing of cell A, using the mean diameter of
