According to the Can Manufacturers Institute, the energy used to make an aluminum can from recycled aluminum is 5% of the energy
used to make an aluminum can from virgin ore. In a typical year, 1.7 billion pounds of aluminum cans are recycled.

Answer:
Width of sound beam is 7.557 m
Explanation:
First we will calculate the wave length from given data:
λ=v/f
Were:
v is the speed
f is the frequency
We considered the opening long and narrow, Using single slit diffraction formula:
mλ=dsinΘ
where:
d is the crack width
m is the order
Θ is angle
Considering m=1, The angle between first minimum from center of beam is:
The width of beam is:
tanΘ=y/L
Width=7.557 m
