What are all the digits of pie?
Artemon [7]

'Pi' is an irrational number.  It can never be completely written with digits.

Here are the first 15 decimal places:    3.14159 26535 89792

A supercomputer lab in Japan has calculated <u>4 trillion</u> digits of pi,
and it still doesn't end. 

With higher mathematics, it's possible to <u>prove</u> that pi never ends.
So, no matter how many digits somebody gives you for pi, there are
still an infinite number more after those.

The point A(-2, 3) is translated using T: (x,y) → (x + 4, y + 2). What is the distance from A to A'? 2 5 2
stepan [7]

For this case, we have that by definition, the distance between two points is given by:

d = \sqrt {(x_ {2} -x_ {1}) ^ 2+ (y_ {2} -y_ {1}) ^ 2}

We have to:

A: (x_ {1}, y_ {1}) = (- 2,3)\\A ':( x_ {2}, y_ {2}) = (x + 4, y + 2) = (- 2 + 4, 3 + 2) = (2,5)

Substituting:

d = \sqrt {(2 - (- 2)) ^ 2+ (5-3) ^ 2}\\d = \sqrt {(4) ^ 2 + (2) ^ 2}\\d = \sqrt {16 + 4}\\d = \sqrt {20}

Answer:

d = \sqrt {20}

The volume of a cone is given by the formula ...

  V = (1/3)πr^2·h

Putting your numbers in, we have ...

  V = (1/3)π(4 ft)^2·(10 ft) = (160π/3) ft^3 ≈ 168 ft^3
