sqare root of 145. my approximation... 12.0398 cm

A = 3.14(Pi) x r2 So, if radius is 4 inches, then A = 3.14 x (4 in. x 4 in.)

A = 3.14 x 16

A = 50.24 in. 3.14 is just an approximation to Pi of course, we could use more digits of Pi if we need it.

There is none, it continues to multiply and go on and on.

The answer depends on 1 billion WHAT! And since you have not bothered to share that crucial bit of information, I cannot provide a more useful answer.

When pi is written digitally, it never ends and never repeats, because it is an infinite number.

This is just the beginning, though: 3.14159265358979323846…

most likely 18

It depends on what you are trying to solve for. Here is a solution for x... y = mx + b y - b = mx (y - b) / m = x Note: If m is zero, then there is no solution, because the line is horizontal

Each side can have any length in the range (0, 12.9) units. The only restriction is that the sum of the seven sides must be 12.9 units.

-2

Divide both sides by -14

x = 4

-4

A = pi*r2

Differentiating with respect to time, t

dA/dt = pi*2r*dr/dt

That is, rate of change in area = pi*2*10*2 m2 per second

= 125.66 m2 per second

Incidentally, 2m / second is a pretty fast wave in water.

usually they are invisible. the way to log in is set up from the settings. press some hotkeys to show it such as ctrl+alt+shift+z.

5 x tenth (.1) = .5

2 x fourth (.25) = .5

.5 = .5

Yes.

That isnt really a normal question so let me tr to explain: in order to find the volume (v) of a rectangular prism (3d rectangle ) you multiply length of one of the sides (use either the "top" or "bottom" )by its width and then multiply that by the Hight of the rectangular prism. Hope this helps!

As it appears, the question does not make any sense.

9.46 + 0*(2+3+5+8) is the simplest solution.

It is a linear equation in 2 variables, x and y. It cannot be solved for either x nor y without another, independent equation.

The ordered pair is (-1, -7).

You mean 6 times 2 plus x plus 2? Well, do all the easy steps first, the is BEDMAS. If you don't know what it is. It's the order of doing operations:

Brackets then exponent then division AND multiplication then addition AND subtraction.

There is no brackets or exponents here, so we do 6 x 2 first

6 x 2 = 12 (We just have to accept to this cruel fact)

so it becomes

12 + x + 2

Addition is associative, at least over the integers, which is what these looks like. That is a + b = b + a for any a, b of choice. Or you can call it shuffle (signs carry, so 5 - 2 = -2 + 5 whatever -2 means)

so 12 + (+x) + (+2) = 12 + 2 + x, BEDMAS continues, we may do 12 + 2 = 14

so you get

14 + x.

What the heck is 14 + x? I don't know? You don't know? But who cares! This is pretty nice looking already. So it's simply 14 + x.

They intersect when 2x + 4 = -x + 1 or 3x = -3 => x = -1

and when x = -1, y = -x + 1 = -(-1) + 1 = 2

So the point of intersection is (-1, 2)
