If A=pir2
and we know A = 16pi
All we need to do is find the square root of pi, which is 4. 4*4 = 16.
So, the radius of the circle is 4.
Answer:
The combined area of two circles with the same radius is 2 πr². The area of a circle with twice the radius is 4 πr². The combined area of two circles is not the same as the area of a circle with twice the radius.
