Option C:
Perimeter of the
of a circle = 10.71 cm
Solution:
Given figure is
of a circle.
It is a quarter of a circle.
Radius = 3 cm, Value of <em>π</em> = 3.14
To find the perimeter of the quarter of a circle.
Perimeter of the quarter of a circle formula: 



Perimeter of the quarter of a circle = 10.71 cm
Option C: 10.7 is the correct answer.
Hence perimeter of the
of a circle is 10.71 cm.

Complete Question
The complete qustion is shown on the first uploaded image
Answer:
The correct option is B
Step-by-step explanation:
From the question we are told that
The sample size is 
The mean is 
The standard deviation is 
Generally the standard error of this measurement is mathematically represented as
substituting values
ppb
Now the probability that the mean lead level from the sample of 49 measurements T is less than 15 ppb represented as P(X < 15 )
Next is to find the z value


Now checking the z-table for the z-score of -1 we have
