A stack of one dozen cookies of diameter 5 in. exactly fits in a cylindrical container of volume 176.715. Which is the thickness of each cookie?

Sagot :

Answer:

The thickness of each cookie = 0.75 in

Explanation:

Given:

A dozen cookie each with 5 in diameter

Volume of the cylindrical container = 176.715 in³

To find:

the thickness (height) of each cookie

To determine the thickness of each of the cookie, we will apply the volume of cylinder:

[tex]Volume\text{ of a cylinder = \pi r}^2h[/tex]

Since there are 12 cookies (a dozen), the volume of the cylinder will be the sum of the volume of each of the 12 cookies

[tex]\begin{gathered} Volume\text{ of the cylindrical container = 12}\times\text{\lparen\pi r}^2h) \\ let\text{ \pi= 3.14} \\ diamete\text{r = 2\lparen radius\rparen} \\ radius\text{ = diameter/2 = 5/2} \\ radius\text{ = 2.5 in} \\ \\ 176.715\text{ = 12}\times\text{3.14 }\times\text{ 2.5}^2\text{ }\times\text{ h} \end{gathered}[/tex][tex]\begin{gathered} 176.715\text{ = 235.5h} \\ h\text{ = }\frac{176.715}{235.5} \\ h\text{ = 0.75 in} \end{gathered}[/tex]

The thickness of each cookie = 0.75 in
