8.53m - 1.8m = 6.73m
Rounded to the less precise measurement would be 6.7. Therefore 6.7m is the answer.
Answer:
The answer is option D.
Step-by-step explanation:

Hope this helps you
Step-by-step explanation:
Margin of error = critical value × standard error
ME = CV × SE
At 95% confidence and 20 degrees of freedom, CV = 2.086.
SE = s / √n
SE = 0.16 / √21
SE = 0.035
So the margin of error is:
ME = 2.086 × 0.035
ME = 0.073
A=pir^2
a=pi13^2
a=169pi
a=530.66 square cm
