Answer: 63.62 square m.
Step-by-step explanation:
Find the Radius so 9/2= 4.5
Area = π r²
Area 3.14(20.25)
Area equles 63.62
The answer is 7.14%
Your ruler measuring centimeters has lines for each centimeter. The rule for error is anything between 6.5 and 7.5 is considered 7cm. So the degree of error is plus or minus .5cm.
Your aim is 7cm so you divide your error of .5 by your target measurement. .5/7= 7.14 percent.
