(4/9)^-1= A. -4/9 B. 9/4 C. -9/4

Romashka-Z-Leto [24]

Answer: 9/4

Step-by-step explanation: Think of $(\frac{4}{9})^{-1}$ as $\frac{4^{-1} }{9^{-1}}$ .

Now, we can change 4⁻¹ to 4¹ by moving it to the denominator and

we can change 9⁻¹ to 9¹ by moving it to the numerator.

So we have 9¹/4¹ which simplifies to 9/4.

What are the lateral area and the surface of the cone shown below?

Ierofanga [76]

$\bf \textit{lateral surface area of a cone}\\\\
LA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}\implies LA=\pi (11)(24)
\\\\\\
\boxed{LA=264\pi }\\\\
-------------------------------$

$\bf \textit{total surface area of a cone}\\\\
SA=\pi r\stackrel{slant~height}{\sqrt{r^2+h^2}}+\pi r^2~~
\begin{cases}
r=radius\\
h=height\\
-------\\
r=11\\
\stackrel{slant~height}{\sqrt{r^2+h^2}}=24
\end{cases}
\\\\\\
SA=\pi (11)(24)+\pi (11)^2\implies SA=264\pi +121\pi 
\\\\\\
\boxed{SA=385\pi }$
