2391m^2
V = (4/3)πR^3

<span>A = 4πR^2 </span>

<span>Given that V = 3500π m^3, you can determine that </span>
<span>(4/3)R^3 = 3500 m^3 </span>
<span>R^3 = 2625 m^3 </span>
<span>R = (2625)^(1/3) m = about 13.795 m </span>

<span>Now plug that into your equation for A: </span>
<span>A = 4πR^2 = 4π(13.795)^2 m^2 = about 2391 m^2</span>

So taking this as if there are 13 dozens of cookies. First we do 13 times 12 which would be 156 cookies in total. Then 156 cookies times 2.08 is 324.48

Answer:

x = 25/4

Step-by-step explanation:

Because of the known similarity of the triangles, we know that

10 x

----- = ----

16 10

Cross-multiplying, we get 16x = 100, and thus x = 100/16 = 50/8 = 25/4

x = 25/4

Archimedes (ca. 287-212 B.C.) was able to use clever geometric means to determine the relative volumes of a cylinder and the con

VLD [36.1K]

Answer:

The ration of the volume of cone to that of cylinder is $\frac{V_{cone}}{V_{cy}} = \frac{1}{3}$

Step-by-step explanation:

From the question we are told that

The volume of a cone is mathematically represented as

$V_{cone} = \frac{1}{3} \pi r^2 h$

The volume of a cylinder is mathematically represented as

$V_{cy} = \pi r^2 h$

Now the ratio we are to obtain is

$\frac{V_{cone}}{V_{cy}} = \frac{\frac{1}{3} \pi r^2 h}{\pi r^2 h}$

$\frac{V_{cone}}{V_{cy}} = \frac{\frac{1}{3} }{1}$ Note: this is possible because the height and base

$\frac{V_{cone}}{V_{cy}} = \frac{1}{3}$ radius are the same
