What is Area of Circle?
A circle's area is the area that it takes up in a two-dimensional plane.
The formula for area of circle is, A = πr², where r is the radius of the circle. The unit of area is the square unit, such as m², cm², etc.
Given:
Radius= 40 mm
So, Area of petri dish = πr²
= 3.14x(40 mm)²
= 3.14 x 1600 mm²
= 5024 mm²
and, Population Density
= 2100 / 5024
= 0.418 bacteria per mm²
Hence, the population density is 0.418 bacteria per mm².

Area = πr^2
= 3.14•(40 mm)^2
= 3.14•1600 mm^2
= 5024 mm^2
Pop Density = 2100 / 5024
= 0.418 bacteria per mm^2
The answer is 0.42 bacteria per square mm
