Question

I NEED HELP PLEASEEEEEEEEEEEEEEEE

Answer 1

The 10 CM represents the diameter of the circle. The diameter is the length of one endpoint to the other. The diameter also must symmetrically split the circle into two semi-circles.

So then we put the 10 cm, around the circle. If we keep doing it, we get 3 full 10 cm around the circle so that

`10 + 10 + 10 = 30`

or

`10 * 3 = 30`

However, we are left with a small fraction of the arc length left, based on mathematicians, that length is approximate 0.14% of the length of the diameter. The length is the diameter is 10 so 0.14% of that is

`(14)/(100) = (x)/(10)`

`140 = 100x`

`x = 1.4`

Now, we add that to 30 so we get

`30 + 1.4 = 31.4`

So the length or circumference of the circle is 31.4.

P.s( we just derive the formula of the concept, of the infamous mathematical symbol)

`\pi`
