Answer:
6.69 cm
Step-by-step explanation:
Given data
Diameter= 12cm
Radius= 6cm
Volume= 757.36cm^3
The expression for the volume of a cylinder is
V= πr^2h
Substitute
757.36= 3.142*6^2*h
757.36=113.112h
h= 757.36/113.112
h= 6.69 cm
Answer:
3.5%
Step-by-step explanation:
The volume of a cylinder =
<em>r</em> = radius of cylinder,
<em>h</em> = height of cylinder
For the non-optimal can,
<em>r</em> = 2.75/2 = 1.375
<em>h</em> = 5.0
<em />
For the optimal can,
<em>d</em>/<em>h</em> = 1,
<em>d</em> = <em>h</em>
2<em>r </em>=<em> h</em>
<em>r</em> = h/2
They have the same volume.
<em /><em />
(This is the height of the optimal can)
(This is the radius of the optimal can)
The area of a cylinder is
<em /><em />
For the non-optimal can,
For the optimal can,
Amount of aluminum saved, as a percentage of the amount used to make the optimal cans =
