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!

The answer is competition for natural resources will increase. More people means people will fight for limited natural resources. It’s the only one that seems logical. Oxygen will not increase since humans do not produce it, we cut down the trees and plants that do to build our houses. More land will not be available it will decrease as more people inhabit the planet and take up more space. People will use more fossil fuels because more people = companies take advantage to sell their product. They don’t care about the environment so if the demand goes up then they will supply more. Even though there’s a limited amount, therefore meaning that the overall amount will decrease.
