Answer:
201 ft³ (201 cubic feet)
Step-by-step explanation:
The volume of a cylinder is given as:
V = pi * r² * h
Where r = radius of the cylinder
h = length of the cylinder.
The diameter of the cylindrical pipe, d = 4 ft
The radius of the cylindrical pipe, r = d/2 = 4 / 2 = 2 ft
The length of the cylindrical pipe, h = 16 ft
The volume of the cylindrical pipe is:
V = 3.14 * 2² * 16
V = 200.96 ft³ = 201 ft³ (to the nearest whole number)
The volume of the cylindrical pipe is 201 ft³ (201 cubic feet)
In the given question, it is already given that the 16 ounce feeder can feed about 80 humming birds. It has to be found the number of birds that a 12 ounce feeder can feed.
Now coming back to the problem.
The number of humming birds that a 16 ounce feeder can feed = 80
The number of humming birds that 1 ounce feeder can feed = (80/16) * 1
= 5 * 1
= 5 birds
Then
The number of humming birds that a 12 ounce feeder can feed = (12 * 5) birds
= 60 birds
So a 12 ounce feeder can feed 60 humming birds.
