20,809,204 is the answer because 20,000,000+800,000+9,000+200+4
Answer: step by step explanation
it's just that you have to multiply the number under root and it's any number is square then you can take it out of root.

notice, if the original area was πr², then the new area has a factor in front of it, that much.
Absolute value, aka same distance from 0
for example |5| is five numbers away from zero and |-5| is also five numbers away from zero
Given that the point B is (1,1) is rotate 90° counterclockwise around the origin.
We need to determine the coordinates of the resulting point B'.
<u>Coordinates of the point B':</u>
The general rule to rotate the point 90° counterclockwise around the origin is given by

The new coordinate can be determined by interchanging the coordinates of x and y and changing the sign of y.
Now, we shall determine the coordinates of the point B' by substituting (1,1) in the general rule.
Thus, we have;
Coordinates of B' = 
Thus, the coordinates of the resulting point B' is (-1,1)
