What do you mean by this? Do you have a picture
The first thing we must do for this case is to calculate the volume of the can using the largest diameter:
V = pi * ((d / 2) ^ 2) * (h)
Where,
h: height
d: diameter.
Calculating we have:
V = pi * ((2.60 / 2) ^ 2) * (4.83) = 25.64 in ^ 3
Then, to determine the amount of liquid in millimeters, we can use a simple rule of three:
1 in ^ 3 ---> 16.3891 milliliters
25.64 in ^ 3 ---> x
Clearing x we have:
x = ((25.64) / (1)) * (16.3891) = 420.22 mm
answer
The amount of liquid that has been bottled in milliliters is 420.22 mm
The convex mirror in the park is an illustration of lens magnification
The man must focus his eyes at 4.50 meters to see his image
<h3>How to determine the object distance?</h3>
The given parameter is:
Radius of curvature, r = 3.00 m
The magnification (m) of the mirror is 1/2, because the image (v) is half as tall as the actual height (u).
So, we have:
m = u/v
So, we have:
u/v = 1/2
Make v the subject
v = 2u
The focal length is calculated as:
1/f = 1/u + 1/v
The focal length is calculated as:
f = r/2
f = 3/2
Substitute f = 3/2 in 1/f = 1/u + 1/v
2/3 = 1/u + 1/v
Substitute v = 2u in 2/3 = 1/u + 1/v
2/3 = 1/u + 1/2u
Take the LCM
2/3 = (2 + 1)/2u
This gives
2/3 = 3/2u
Take the inverse of both sides
3/2 = 2u/3
Cross multiply
2u = 3 * 3
4u = 9
Divide both sides by 4
u = 9/4
This gives
u = 2.25
Recall that:
v = 2u
So,we have:
v = 2 * 2.25
v = 4.50
Hence, the man must focus his eyes at 4.50 meters to see his image
