$\bf \textit{surface area of a cylinder}\\\\
SA=2\pi r(h+r)~~
\begin{cases}
r=3.5\\
h=12
\end{cases}\implies SA=2\pi (3.5)(12+3.5)
\\\\\\
SA=7\pi (15.5)\implies SA=108.5\pi$

Solve the equation.

Dafna1 [17]

Hi there!

Here are all the steps into solving this equation :

$\frac{9z+4}{5}$ - 8 = 5.4

Add 8 on each side of the equation → 5.4 + 8 = 13.4

$\frac{9z+4}{5}$ = 13.4

Multiply each side of the equation by 5 → 13.4 × 5 = 67

9z + 4 = 67

Subtract 4 from each side of the equation → 67 - 4 = 63

9z = 63

Divide each side of the equation by 9 → 63 ÷ 9 = 7

z = 7

There you go! I really hope this helped, if there's anything just let me know! :)
