Incomplete question. However, I inferred you are referring to May 14, 2015, theconversation online article by Manu Saunders a Post-doctoral Research Fellow (Ecology), at Charles Sturt University.
<u>Explanation:</u>
The article stresses the consequences of single-crop farming on wildlife survival in other to allow for biodiversity. Specifically, she focuses on the impact of single-crop farming on wild pollinators such as native bees and hoverflies.
Therefore, according to Manu's research, this pollinators have restricted access to diverse resources as a result of single-crop farming; which leads us to the central theme; Single-Crop Farming Is Leaving Wildlife With No Room To Turn.
Formula of circle:
C= 2πr
The radius is half of the diameter, so divide 9 by 2
18/2=9
Then plug in 9 as the radius in the formula.
C= 2π(9)
Using you calculator multiply 2 by the symbol "π" and 9
Exact Form is 18π
Decimal Form is 56.54866776...
I'm pretty sure that its because of Tybalt
