Answer:
1. 8.3%
Step-by-step explanation:
Relative error = absolute error/expected measurement
The expected measurement is given as 6 ft.
Now, the absolute error is usually equal to half of a unit of the measure.
This means the absolute error in this case is ½ × 1 = 0.5 ft
Thus, the exact measurement will be;
6 ± 0.5
Thus;
Relative error = 0.5/6
Relative error = 0.083
Expressing it in percentage gives 8.3%
Answer:
40
Step-by-step explanation:
6x7-8/4 =42 - 2 = 40
Answer:
A.
Step-by-step explanation:
The formula for circumference is:
We know that the circumference is 8π inches. So, substitute 8π for C:
Solve for r. Divide both sides by 2π. So:
Therefore, the radius is 4 inches.
Hence, our answer is A.
