Answer:

Step-by-step explanation:
Just carry the decimal point over to the right 4 places.
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
The answer of t he trapezoid area problem is 112.
