The expression C.
cubic
represents the bacterium's volume.
Step-by-step explanation:
Step 1:
The E. Coli bacterium is in the shape of a cylinder.
The volume of a cylinder is given by multiplying π with the square of the radius (r²) and the height of the cylinder.
The volume of a cylinder, 
In the given diagram, E. Coli has a radius of 1
and a height of 0.5
.
Step 2:
By substituting the values in the equation, we get
The volume of the E. Coli bacterium
cubic
.
This is option C.
25.59- 9.99= 15.60
15.60/ 0.05 = 312
