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.
Answer:
When we are dealing with area (2 dimensions) the decrease is (1/8) squared or 0.0156250
So 34 sq meters * 0.0156250 = 0.53125 sq meters
A square meter = 100*100 cm = 10,000 sq centimeters.
So .53125 sq meters times 10,000 = 5,312.5 sq centimeters
I double-checked my answer and it seems the answer is 5,312.5 sq cm.
I'm guessing whoever made this question, when they converted square meters to square centimeters, they divided by 100 instead of 10,000.
