There are approximately Pi times 10,000,000 seconds in one ____?
MissTica

The number of seconds in a year are 31,557,600 seconds, which gives;

There are approximately Pi times 10,000,000 seconds in one <u>year</u>.

<u />

<h3>How can the given statement be completed?</h3>

The number of seconds in one day = 86,400

The number of seconds in one week = 604,800

The number of seconds in a year = 31,557,600

Therefore;

\mathbf{\dfrac{The \ number  \ of  \ seconds  \ in \  a \  year}{10,000,000}}  = 3.1557600 \ which  \ is \ close \ to \3.14159 \approx \pi

Which gives;

The number of seconds in a year ≈ π × 10,000,000

The completed statement is therefore;

  • There are approximately Pi times 10,000,000 seconds in one <u>year</u>

A box with a square base and no top is to be built with a volume of 4000 in3. find the dimensions of the box that requires the l
vekshin1

Let the length of the square base be x inches .

And the height of the box be y inch .

Volume = x*x*y

4000 = x *x *y

y = \frac{4000}{x^2}

S = x*x + 2xy + 2 x y

S = x^2 + 4 xy

S = x^2+ 4x* \frac{4000}{x^2}

S = x^2 + \frac{16000}{x}

S ' = 2x - \frac{16000}{x^2}

S ' =0

2x - \frac{16000}{x^2}=0

2x^3 - 16000 = 0

x^3 = 8000

x = 20

y =  \frac{4000}{20^2} = \frac{4000}{400} = 10
