Step-by-step explanation:
Answer: A
explanation: the vertex in this graph is the lowest point, making it a minimum vertex. If it was the highest point, it would be maximum
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.
