Calculating Average Pollutant Concentration

Question

The pollutant concentration as a function of distance from an industrial center is given by $$P(r)= 200*e^{-0.05*r}$$ (in μg/m³). Estimate the average concentration within a circle of radius 10 km.

Accepted Answer

Approximately $$144.4$$ μg/m³.

Answer

Approximately $$160$$ μg/m³, stemming from an approximate error in the area calculation.

Answer

Approximately $$200$$ μg/m³, if the maximum value is incorrectly assumed to be uniform.

Answer

Approximately $$100$$ μg/m³, reflecting an undervaluation of the integrated concentration.
