Alana makes soup and packages it in conical containers that each have a height of 5 inches. What is the radius of each container of a pack of 12 containers contains 203.5 inches of soup? Use 3.14 to represent pi and round to the nearest tenth

Sagot :

We are given that 12 cones contain 203.5 cubic inches. Since there a re 12, the volume of each individual cone is:

[tex]V=\frac{203.5in^3}{12}=16.96in^3[/tex]

Now, the volume of a cone is given by the following formula:

[tex]V=\frac{1}{3}\pi r^2h[/tex]

Where "r" is the radius and "h" the height. Solving for the radius first by multiplying by 3:

[tex]3V=\pi r^2h[/tex]

Now we divide both sides by pi:

[tex]\frac{3V}{\pi}=r^2h[/tex]

Now we divide both sides by "h":

[tex]\frac{3V}{\pi h}=r^2[/tex]

Now we take the square root to both sides:

[tex]\sqrt[]{\frac{3V}{\pi h}}=r[/tex]

Now we replace the known values:

[tex]\sqrt[]{\frac{3\mleft(16.96in^3\mright)}{\mleft(3.14\mright)\mleft(5in\mright)}}=r[/tex]

Solving the operations:

[tex]\sqrt[]{\frac{50.88in^2}{15.7}}=r[/tex][tex]\sqrt[]{3.2in^2}=r[/tex][tex]1.8in=r[/tex]

Therefore, the radius is 1.8 inches.
