The circumference of a circle with an area of 1,809.56 square centimeters

Virty [35]

$\bf \textit{area of a circle}\\\\
A=\pi r^2~~
\begin{cases}
r=radius\\
------\\
A=1809.56
\end{cases}\implies 1809.56=\pi r^2
\\\\\\
\cfrac{1809.56}{\pi }=r^2\implies \boxed{\sqrt{\cfrac{1809.56}{\pi }}=r}\\\\
-------------------------------\\\\
\textit{circumference of a circle}\\\\
C=2\pi r\qquad \qquad \implies C=2\pi \left( \boxed{\sqrt{\cfrac{1809.56}{\pi }}} \right)$

How can you solve an equation with the variable on both sides?

diamong [38]

You should move the variable to the same side!

best by addition/substraction:

for example:

2x+5=3x

I will "move" the 3x:

2x+5-3x=0

now you can add up the variables: -x+5=0 (x=5)

essentially you can move it to the other side, changing the sign: + to -, - to +
