CF=EC=DC
2CF=CD
CD = 20 in.
Answer:
≈ 93.06 cm²
Step-by-step explanation:
Subtract the area of the rectangle from the area of the circle
area of circle = πr² = π × 8² = 64π cm²
area of rectangle = 12 × 8 = 108 cm²
Thus
shaded area = 64π - 108 = 201.062 - 108 ≈ 93.05 cm² ( nearest hundredth )
Answer:
Option C is correct.
The value of r=0.2 represents the weakest correlation.
Step-by-step explanation:
Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.
Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.
From the options, the only r-value that is very close to 0 is 0.2.
Therefore, the r-value represents the weakest correlation is, 0.2
The greatest common factor is 2 so divide the numerator and denominator by 2 to get:
1/5
