\textit{volume of a cylinder}\\\\ V=\pi r^2 h~~ \begin{cases} r=radius\\ h=height\\[-0.5em] \hrulefill\\ V=2034.72\\ h=18 \end{cases}\implies 2034.72=\pi r^2(18) \implies \cfrac{2034.72}{18\pi }=r^2 \\\\\\ \cfrac{2034.72}{18(3.14) }=r^2\implies \sqrt{\cfrac{2034.72}{18(3.14) }}=r\implies 6=r

Solve 3^2x-5=81<br> Please show work
Strike441 [17]
Let's solve your equation step by step
(3^2)(x)-5=81
step 1:simplify both sides of the equation
(3^2)(x)-5=81
simplify.
9x-5=81
step 2:Add 5 to both sides.
9x-5+5=81+5
9x=86
divide both sides by 9.
9x/9=86/9
x=86/9
Answer:86/9

Hope this helps!
