Answer:
B, D, and E
Explanation:
First, the formula for the area of a circle is
Since pi is equal to 3.14, all we need is the radius squared. Since your radius is 12, =144. Therefore, your equation for <em>area</em> will be (3.14)(144), answer B.
Second, the formula for the circumference of a circle is .
So, 2(3.14)(12), answer D.
Edit: Answer E also says the same as above- it just multiples the 2 and the 12 together. Sorry for the initial error!
For larger populations, you need more agriculture. Thefore, the agriculture industry has to work even harder to provide.
<span>Fossils symbol and mountain belts are very important
for geologists in deciding where to move the continents.
Fossils and mountain belts can give the
geologist ideas about the history of the certain continents and what are the
animals that stayed and died in that place.
Both can also help the geologists to identify if the particular continent is a
safe place to live on because the animals of a long time ago stayed on that
place. So maybe the place is safe from water high tide and is not a moving
plates.</span>
