Question 985886: Rhinoviruses, which are the leading cause of the common cold, have a diameter of 20 nanometers(20 × 10−9meter). Pneumococcus, a bacterium causing pneumonia, measures about 1 micron(10−6meter) in diameter. How many times as large in diameter as the virus is the bacterium?

You can put this solution on YOUR website! Rhinoviruses, which are the leading cause of the common cold, have a diameter of 20 nanometers(20 × 10−9meter). Pneumococcus, a bacterium causing pneumonia, measures about 1 micron(10−6meter) in diameter. How many times as large in diameter as the virus is the bacterium?
================
1e-6/20e-9 = (1/20)e3 = 0.05*1000
= 50 times
---------------
50 times the diameter --> ~125000 times the volume
