Pi is the ratio between the circumference of a circle and the diameter of said circle. Usually it is represented by these three things: π, 3.14, 22/7

30/(1/2)+10

30*2+10

60+10

70.

Doing π*2, you get:6.2831853071795865

Pressing π twice you get:9.8696044010893586, or π²

Or you can see that they are the same fraction and ta-da. Your answer is..... NO. I KNOW WHAT YOURE DOING. THE ANSWER IS 21 BUT IM NOT GOING TO SAY IT. DARN IT I SAID IT.

You can also move the decimal an amount of spaces until you have 1 digit in front of the decimal.

1  8  2  0  0  0.

There are 6 digits and we need to make it 1 digit in front of the decimal point.

6-x=1

182000=1.82*10^x

Find the value of x.

-x+6=1

   -6   -6

-x=-5

--   --

-1   -1

x=5, so the scientific notation is 1.82*10⁵
