the lateral area of a cone is 574 pi cm2. The radius is 19.6 cm. What is the slant height to the nearest tenth of a centimeter?

bulgar [2K]

$\bf \textit{lateral area of a cone}\\\\
LA=\pi r\sqrt{r^2+h^2}~~
\begin{cases}
r=radius\\
\sqrt{r^2+h^2}=slant~height\\
-----------\\
LA=574\pi \\
r=19.6
\end{cases}
\\\\\\
574\pi =\pi (19.6)\sqrt{r^2+h^2}\implies \cfrac{574\pi }{19.6\pi }=\sqrt{r^2+h^2}
\\\\\\
\cfrac{574}{19.6}=\sqrt{r^2+h^2}$

Rewrite the product (x-3)^2 in standard form. Show your work

arsen [322]

Answer:

x² - 6x + 9

Step-by-step explanation:

(x - 3)²

= (x - 3)(x - 3)

Each term in the second factor is multiplied by each term in the first factor

= x(x - 3) - 3(x - 3) ← distribute both parenthesis

= x² - 3x - 3x + 9 ← collect like terms

= x² - 6x + 9 ← in standard form

leva [86]

Answer:

81000 $cm^{2}$ or 8.1 $m^{2}$

Step-by-step explanation:

1m = 100cm

10m = 1000cm

a= b*h

a= 1000cm * 810cm

= 810000 $cm^{2}$

1 $m^{2}$ = 10000 $cm^{2}$

810000 $cm^{2}$ = 8.1 $m^{2}$

3 over 5 is 30% of what number?

denis23 [38]

3/5 = 0.3 * x
3/5 is 30% of x - This is how they match up from the word problem to a number sentence

So to solve it...
3/5 = 0.3x
x = 3/5 ÷ 0.3 = 2
