<u>Lateral Surface Area of a Cone</u>

Given a right circular cone of base radius r and height h, the lateral surface area is given by:

$A=\pi r\sqrt{r^2+h^2}$

We are given the lateral area of a funnel as A=236.64 square cm and the radius is r=4.75 cm. It's required to find the height of the cone. It can be calculated by solving for h.

Squaring:

$A^2=\pi^2 r^2(r^2+h^2)$

Dividing by $\pi r^2$

$\displaystyle \frac{A^2}{\pi^2 r^2}=r^2+h^2$

Subtracting $r^2$ :

$\displaystyle \frac{A^2}{\pi^2 r^2}-r^2=h^2$

Taking square root:

$\displaystyle h=\sqrt{ \frac{A^2}{\pi^2 r^2}-r^2}$

Substituting the values:

$\displaystyle h=\sqrt{ 251.472-22.5625}$

$\displaystyle h=\sqrt{ 228.909}$

h = 15.13 cm

A secretary can type 12 pages per hour. There are a total of 152 pages to type. How many pages remain to be typed after 9 hours?

mr_godi [17]

So, she can type 12 pages in 1 hour, how many would she type in 9 hours then? let's check,

$\bf \begin{array}{ccll}
pages&hours\\
\text{\textemdash\textemdash\textemdash}&\text{\textemdash\textemdash\textemdash}\\
12&1\\
p&9
\end{array}\implies \cfrac{12}{p}=\cfrac{1}{9}\implies \cfrac{12\cdot 9}{1}=p$

so in 9 hours, she has that typed that many pages, how many pages remain from the 152? well 152 - p.
