The answer to the question is a)
Given problem;
A =
r²
Solve for π;
To solve for π implies that we make it the subject of the expression.
So;
A = π r²
Now multiply both sides by ![\frac{1}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7B1%7D%7Br%5E%7B2%7D%20%7D)
So;
A x
=
x r² x
r² cancels out from the right side and leaves only π;
π = ![\frac{A}{r^{2} }](https://tex.z-dn.net/?f=%5Cfrac%7BA%7D%7Br%5E%7B2%7D%20%7D)
So ![\pi = \frac{A}{r^{2} }](https://tex.z-dn.net/?f=%5Cpi%20%20%3D%20%5Cfrac%7BA%7D%7Br%5E%7B2%7D%20%7D)
Answer:
y+1=-3(x-4)
Step-by-step explanation:
first you want to plug in the numbers into the formula which y-y1=m(x-x1).
then you get y+1=-3(x-4)

Reginald Punnett and William Bateson were among the first English geneticists. Punnett devised the "Punnett Square" to depict the number and variety of genetic combinations, and had a role in shaping the Hardy-Weinberg law. Punnett and Bateson co-discovered "coupling" or gene linkage.
