Answer:

a) 2.5π, b) ≈673 times

Step-by-step explanation:

diameter = 2.5

circumference = diameter*π

circumference = 2.5π

5280/2.5π

≈5280/2.5*3.14

≈5280/7.85

≈672.6, ≈673

snow_lady [41]

ANSWER

Biodiversity index = 0.096

EXPLANATION

Given 7 different organisms with their individual numbers.

Biodiversity Index is:

\text{  }\frac{Total\text{ number of species}}{Total\text{ number of individuals in the area}}

i.e:

\begin{gathered} Biodiversity\text{ Index = }\frac{7}{15+2+30+1+4+16+5} \\ \text{ = }\frac{7}{73} \\ \text{ = 0.09589} \end{gathered}

Hence, the Biodiversity Index of Fraya's local park is 0.096. This is a low biodiversity since it's closer to 0.
