cylinder has radius 2.5 cm and lateral area 20π cm2.20π cm2. 20 pi . cm squared , . What is the surface area of the cylinder in

uysha [10]

$\bf \textit{lateral area of a cylinder}\\\\
LA=2\pi rh\qquad 
\begin{cases}
r=radius\\
h=height\\ -----\\
LA=20\pi \\
r=2.5
\end{cases}\implies 20\pi =2\pi \cdot 2.5h
\\\\\\
\cfrac{20\pi }{2\cdot 2.5\pi }=h\implies \boxed{4=h}\\\\
-------------------------------\\\\
\textit{total surface area of a cylinder}\\\\
SA=2\pi r(h+r)\implies SA=2\pi \cdot 2.5(4+2.5)$

It's the slope of the secant line to <em>f(x)</em> through the points (-3, <em>f</em> (-3)) and (9, <em>f</em> (9)),

$\dfrac{f(9) - f(-3)}{9 - (-3)} = \dfrac{-7 - 1}{12} = -\dfrac8{12} = \boxed{-\dfrac23}$
