2/96 = 0.0208333333333333

The circumfrance of 29... uh... units is the amount of said units you can wrap around the circle you got the data of the circumfrance from. (I don't know what you meant by this but this is what I infered your question to be).

2-D figures are flat for one thing such as a square or a triangle. On the other hand 3-D figures have depth some examples being cubes or a sphere.

There is a button called arcsin, this is equivalent to ${sin}^{-1}$

Hope this helped.

This question is more conceptual than mathematical, so it's understandable that you don't get it.

My guess is that A is the answer. Reason being, if you see the pattern in the snow height and speeding cars, the ratio DOES indeed decrease as the snow height increase.

Well that depends on the kind of answer you want exact or an estimate.

Estimate (just punch it into a calculator):

 2.6457513110645906

Exact (cannot be simplified):

$\sqrt{7}$

Nope. Simply put, we cannot fathom the amount of mathematical... what's the word... I'll just say math. It would be impossible to stop advancing in math, especially to stop working on it. Mathematical applications are all over, everywhere you look, there may even be some which humanity has not discovered yet. I had a debate with my Calculus teacher about this, he told me something that kind of blew my mind, "Just as math can go to infinity, so can mankind."

Let "y" be the amount of words typed and let "x" be the amount of minutes that pass.

If she types 45 words per minute (45 words/ minute), then that should be multiplied by "x" (seconds) in order to cancel out minutes and get words which would be on the other side of the equal side or "y".

Your equation would turn out to be :

y = 45x

The surface area of a sphere is equivilent to A = 4πr^2.

All you need to do is plug in (π/9) for A and solve for r.

(π/9) = 4πr^2

Divide 4 on both sides:

(π/36) = πr^2

Divide π on both sies:

(1/36) = r^2

Take the square root of both sides:

1/6 = r

Use appropiate units and get...

Radius = 1/6 feet
