Question

Bacteria vary somewhat in size, but a diameter of 1.2 μmis not unusual.

What would be the volume (in cubic centimeters) of such a bacterium, assuming that it is spherical?

What would be the volume (in cubic centimeters) of such a bacterium, assuming that it is spherical?

Answer 1

1 m = 10^-4 cm

Diameter of the bacterium = D = 1.2 m

Radius of the bacterium = R = D/2 = 1.2/2 = 0.6 m

Converting the radius of the bacterium from micrometer to centimeter,

R = 0.6 x (10^-4) cm

R = 6 x 10^-5 cm

Volume of the bacterium = V

V = 9.05 x 10^-13 cm³

Volume of the bacterium assuming it is spherical = 9.05 x 10^-13 cm³
