Answer:
1134.11
Step-by-step explanation:
The problem with this equation is pi is an angle in radians. It has a never ending number of digits.
The area of a circle is basically a square r x r rotated through 180 degrees around the squares centre.
So the area can be written as 180 x 19 x 19 = 64980 degrees meters square.
This is a finite number. The area of a circle does not change. Pi r squared has an ever increasing result.
pi is a conversion factor between the finite areas of circles and the area in square units which can never have a result that is finite as squares cannot fill a circle, no matter how small.
To convert the round finite area to m squared you divide the area by 180/pi = 57.295779513 degrees per radian.
Area in degrees meters Squared 64980/ 57.295779513.
= 1134.1149479 radian meters squared.
