The answer should be 112 degrees
I'm guessing the question is meant to be "<span>If the radius of a circle with a area of 5.3 mm squared is multiplied by 5, what will the new area be?", so i'll answer that.
Area of a circle =</span>πr^2
5.3=πr^2, 5.3=π(5r)^2
132.5=25πr^2
-18 +30s -72t +12u is the answer
The answer is 27.1052631579 or 27.1 if you rounded "m" to .10
