Answer:
False. The dimensions of the resulting circle will be 9 times as large
Explanation:
The only dimension a circle has is its radius , r
The area of a circle is given by π
if the radius is tripled, the new radius will become 3r.
hence the new area will become
π ×
= 9π
Hence, the new area will be 9 times as large.
A television station that can be watched by 7 million people has a much greater outreach than a meeting at the city hall with 25,000 people.
<u>Explanation:
</u>
It seems quite obvious that a lot of people own a television. By telecasting programs on a television media, outlets can increase their outreach to a much larger audience.
While a meeting in a city hall filled with 25,000 people can only prove to reach out to the people who are present there, a television program can reach out to people who are not only in that city but who are in other parts of the world too, thus making outreach as the suitable word.
Answer:
In the excercise: Archaeologist: Researchers excavating a burial site in Cyprus found a feline skeleton lying near a human skeleton. Both skeletons were in the same sediment at the same depth and equally well-preserved, suggesting that the feline and human were buried together about 9,500 years ago. This shows that felines were domesticated around the time farming began, when they would have been useful in protecting stores of grain from mice.
Which of the following, if true, would most seriously weaken the archaeologist’s argument? The anser that would weaken the archaeologist's argument is D)In Cyprus, there are many burial sites dating from around 9,500 years ago in which the remains of wild animals appear to have been buried alongside human remains.
Explanation:
This is a very complicated question if we go to the data, but if we recall the evidence we have in this text we can find the next situation: First of all, The text says that around 9500 years ago the bones of human and feline were buried in the same sites, and this fact is used to support a hypothesis of feline domestication. However, if we observe option D) it says that there have been foundings of wild animal bones buried with human remains surrounding 9500 years of the events. So, if we compare both we can't use the fact that because they were buried in the same places they were domesticated and it weakens the hypothesis.
Answer:
Because a lot of things have not yet been discovered and questioned as well as there being billions of things that we have absolutely no knowledge about.
