Hello!

To find the lateral area you use the equation

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

You put in the values you know and you get 829.4

To find the surface area you use the equation

$\pi r(r+ \sqrt{ h^{2} + r^{2} }$

Put in the values you know and you get 1209.5

The answer is A

Hope this helps!

Convert 45° from degrees to radians.

leonid [27]

<h2>pi divided by four</h2>

Step-by-step explanation:

Let the angle in degrees be $a$

Let the angle in radians be $r$

If $a$ is the angle in degrees and $r$ is the angle in radians,

$a\times \frac{\pi }{180}=r$

It is given that the $a=45$

$r=\frac{\pi}{180}\times a= \frac{\pi}{180}\times 45=\frac{\pi}{4}$

So, $r=\frac{\pi}{4}$

Ebony walked at arate of 3 1/2 miles per hour for 1 1/3 how far did she walk?

ElenaW [278]

let's firstly convert the mixed fractions to improper fractions.

$\bf \stackrel{mixed}{3\frac{1}{2}}\implies \cfrac{3\cdot 2+1}{2}\implies \stackrel{improper}{\cfrac{7}{2}}~\hfill \stackrel{mixed}{1\frac{1}{3}}\implies \cfrac{1\cdot 3+1}{3}\implies \stackrel{improper}{\cfrac{4}{3}} \\\\[-0.35em] \rule{34em}{0.25pt}$

$\bf \begin{array}{ccll} miles&hours\\ \cline{1-2}\\ \frac{7}{2}&1\\[0.8em] m&\frac{4}{3} \end{array}\implies \cfrac{~~\frac{7}{2}~~}{m}=\cfrac{~~1~~}{\frac{4}{3}}\implies \cfrac{7}{2m}=\cfrac{3}{4}\implies 28=6m \\\\\\ \cfrac{28}{6}=m\implies \cfrac{14}{3}=m\implies 4\frac{2}{3}=m$
