I know that the formula is A = Pi R*2, but what is the significance of pi? How does it help us with area. Why?

Thanks!

Working with animals is my dream job. Ive never made stright A's or a's and b's all my life and Im not rich. I would love to do something with animals, but im not exactly sure what I want to do. So what are the different jobs that I could have? I want to make decent money and not struggle like my parents did, but money isnt my biggest priority. I just want to live my dream, but im not sure its possible. Any zoologists out there??

Q: A right triangle has one vertex on the graph of y = x^3; x > 0, at (x , y), another at the origin, and the third on the positive y-axis at (0 , y). Express the area A of hte triangle as a function of x.

Here's my work:
Distance from (0,0) to (x,y) on y = x^3 equals d.
d = √[(x^2 + (x^3)^2]
d = √(x^2 + x^6)

Distance from (0,y) to (0,0) equals s.
s = √[(x^3)^2]
s = √(x^6)
s = x^3

Since d is the hypotenuse and s is one leg, to find the other leg (b for base), use:
(x^3)2 + b^2 = (√(x^2 + x^6))^2
x^6 + d^2 = x^2 + x^6
d^2 = x^2
d = x

To find the area, A, of the triangle, you perform
A = 1/2(bh)
A = 1/2(x)(x^3)
A = 1/2(x^4)

Right? There is a picture, with a graph. The right angle is formed at (0,y) and the hypotenuse is from (x,y) to (0,0). If you see anything wrong with my arithmetic, please point it out to me. Thank you, ahead of time.

According to general theory of relativity gravity is always attractive and there is no negative gravitational effect. If gravity is always attractive why the universe is expanding? All the matter is supposed to attract each other and come to one point.

Some one told me they come from wood piles that they are spiders incognito, Some of the redheads I know run like spiders and have behaviors like them too.

I know deaths are really rare, but is there a way to prevent stings? My friend was stung, and she said it was horrible, and now with the death of Steve Irwin, I'm really cautious. I mean, its really hard to tell if something is in the sand when its all muddy.

Write and solve an equality to find three consecutive whole numbers with a sum between 13 and 16.

The length of a sidee of any triangle is less than the sum of the elngths of the other two sides. In (Triangle) PQR, PR = RQ+4 and RQ<11. Write and solve an inequality for PQ.

Help how do i do these?
