Explanation:
The given passage talks about the impact of chemicals on the ecosystem. The speaker narrates how the ecology belongs to plants, animals, and humans, though man seemed intent to destroy it for himself.
The blanks in the given passage are filled with the appropriate words as follows-
Ecology is the study of how <em><u>(1) plants</u></em>, animals, and people live <u><em>(2) together</em></u> and help each other. But man sometimes forgets he <em><u>(3) is</u></em> a part of the <u><em>(4) family</em></u> of all living things. Here is an example. A planter is <u><em>(5) talking</em></u> about killing <u><em>(6) weeds</em></u> on his land. He remembers his first <u><em>(7) experience</em></u> with a weedicide. He was a <u><em>(8) planter</em></u> then, working <u><em>(9) on</em></u> a rubber plantation. He had a problem with weeds. The cost of weeding of the <u><em>(10) fields</em></u> by hand was getting <em><u>(11) too</u></em> high. So he used a new, cheap, and effective <u><em>(12) method</em></u>, good old Sodium Arsenate. He sprayed plenty of this <em><u>(13) around</u></em> to kill the weeds. The first thing to <em><u>(14) react</u></em> were the frogs.
The first thing we are going to do for this case is to model the igloo as a hemisphere.
The volume of the hemisphere is:
V = ((4/3) * (pi) * (r ^ 3)) / 2
Where,
r: sphere radio
We have then that the internal diameter is:
di = 12-1.5
di = 10.5 feet
So the radio is:
r = di / 2
r = 10.5 / 2
r = 5.25 feet
Substituting values:
V = ((4/3) * (pi) * ((5.25) ^ 3)) / 2
V = 303.1 feet ^ 3
Answer:
the amount of space of the living area inside the igloo is:
V = 303.1 feet ^ 3
