How to calculate length of a radius in circle geometry
1 answer:
There are many ways you can calculate the length of a radius of a circle. Let's start with the obvious.
A radius is half the length of a diameter. So if you have the length of a diameter, just divide in half and there's your radius!
If you only have the circumference of a circle, you can use the formula
r = C ÷ (2
)
C being the circumference.
Hope this helped!

Answer:
x is approximately 10.772
Step-by-step explanation:
To solve for x, we convert this log form to exponential form
If
to convert it into exponential form we make log alone
Divide by 3 on both sides
Then divide by 2 on both sides
so x= 10.772

Let be the population mean strain in a way that conveys information about precision and reliability.
The sample mean is the best point estimate of the true population mean .
As per given , we have
Sample size : n= 12
degree of freedom :
Sample mean :
The true average strain in a way that conveys information about precision and reliability= 25.0
sample standard deviation : s= 3.3
Significance level :
Since sample population standard deviation is unknown , so we use t-test.
Critical t-value for t :
95% Confidence interval for true average strain in a way that conveys information about precision and reliability:
The 95% Confidence interval for true average strain in a way that conveys information about precision and reliability:
We 95% confident that the true population average strain in a way that conveys information about precision and reliability lies between 22.9 and 27.1 .
