The best way to justify which answers are correct are to calculate the circumference and the area for each of the circles with the given radii. I organized this information into a chart.
Circumference | Area
1/2 3.14 0.785
1 6.28 3.14
1 1/2 9.42 7.065
2 12.56 12.56
2 1/2 15.7 19.625
The first three choices will result in a numerical value for the radius that is smaller than the area.

Step-by-step explanation:
![Sin N = \frac{Opposite}{hypotenuse}](https://tex.z-dn.net/?f=Sin%20N%20%3D%20%5Cfrac%7BOpposite%7D%7Bhypotenuse%7D)
![sin 7 = \frac{x}{3.4}\\\\3.4 \times sin 7 = x \\\\3.4 \times 0.122 = x \\x = 0.41](https://tex.z-dn.net/?f=sin%207%20%3D%20%5Cfrac%7Bx%7D%7B3.4%7D%5C%5C%5C%5C3.4%20%5Ctimes%20sin%207%20%3D%20x%20%5C%5C%5C%5C3.4%20%5Ctimes%200.122%20%3D%20x%20%5C%5Cx%20%3D%200.41)
