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 =
Answer:
122
Step-by-step explanation:
Plug in 1 for x and 11 for y
1 to the power of any number will always equal 1

Answer:
The area of the circle is 50.24 mm
²
Step-by-step explanation:
To solve this exercise we need to use the area formula of a circle:
a = area
r = radius = 4mm
π = pi = 3.14
a = π * r²
a = 3.14 * (4mm
)²
a = 3.14 * 16mm
²
a = 50.24 mm
²
The area of the circle is 50.24 mm
²
Either the second one or the third one.good luck !
