Answer:

<h2>a =  \frac{8A}{\pi {r}^{2} }  + 1 \\</h2>

Step-by-step explanation:

A =  \frac{1}{8} \pi {r}^{2} (a - 1) \\

First of all multiply through by 8 to eliminate the fraction

That's

8A = 8 \times  \frac{1}{8} \pi {r}^{2} (a - 1) \\8 A = \pi {r}^{2} (a - 1)

<u>Divide both sides by πr²</u>

\frac{8A}{\pi {r}^{2} }  =  \frac{\pi {r}^{2}(a - 1) }{\pi {r}^{2} }  \\ a - 1 =  \frac{8A}{\pi {r}^{2} }

Move 1 to the other side of the equation to make a stand alone

We have the final answer as

a =  \frac{8A}{\pi {r}^{2} }  + 1 \\

Hope this helps you

Can anyone do question 25 part c? :)
inna [77]
\begin{cases}x^3\qquad\qquad\ \ \  when\ x\geq3\\5\qquad\qquad\quad \ when\  0\ \textless \ x\ \textless \ 3\\x^2-x+2\quad\ when\ x\leq0 \end{cases}\\\\\\ (a)\\ f(0)\iff x=0\implies f(x)=x^2-x+2\\\\f(0)=0^2-0+2=2\\\\(b)\\ \{f(2)\iff x=2;\ \ f(1)\iff x=1\}\implies f(x)=5\\\\ f(2)=5\quad\wedge\quad f(1)=5\\\\ f(2)-f(1)=5-5=0

(c)\\ \big\forall \limits_{ n\in R}\ n^2\geq 0\ \ \Rightarrow\ \ \big\forall \limits_{ n\in R}\ (-n^2)\leq 0 \ \ \Rightarrow\ \ x\leq0\ \ \Rightarrow\ \  f(x)=x^2-x+2\\\\f(-n^2)=(-n^2)^2-(-n^2)+2=n^4+n^2+2
