Answer:
4th, 3rd, 1st, 2nd.
Step-by-step explanation:
Comparing the radii will give the same result as comparing the areas because the areas are directly proportional to the square of the radii (that is Area = pi r^2).
The second circle has a radius of 27 units.
The 4th circle has a radius of 19/2 = 9.5 units.
The third circle radius is worked out below:
2 pi r = 87.92 so r = 87.92 / 2 pi = 13.99 units.
The first one has radius = √ (1040.09 / pi ) = 18.2 units.
I did it this way because it was less calculation!
