First you need to divide the area by pi. Then take that answer and square-root it. Your answer should come out to about 3.2 is the radius.
Answer:
-2.8
Step-by-step explanation:
Given that:
Mean, μ = 78
Standard deviation, σ = 5
Omar's score, x = 64
The Zscore of Omar's score :
Zscore = (x - μ) ÷ σ
Zscore = (64 - 78) / 5
Zscore = - 14 / 5
Zscore = - 2.8
Hence, Omar's exam score is - 2.8
The ratio would be 4:1.
Try to reduce the ratio further with the greatest common factor (GCF).
The GCF of 64 and 16 is 16
Divide both terms by the GCF, 16:
64 ÷ 16 = 4
16 ÷ 16 = 1
The ratio 64 : 16 can be reduced to lowest terms by dividing both terms by the GCF = 16 :
64 : 16 = 4 : 1
Therefore:
64 : 16 = 4 : 1
