Find the diameter of a circle with the known circumference of 314” use the formula d= C

siniylev [52]

The complete formula for circumference is:

$C=\pi d$

Since we know the circumference of the circle is 314 inches, we can then solve for d, the diameter:

$314=\pi d$

Using 3.14 for pi, we get:

$314=(3.14)d$

Then solve for d:

$d=100$

And now we know the diameter of the circle is 100 inches.

At winds speeds above 1000 centimeters per second (cm/sec), significant sand-moving events begin to occur. Wind speeds below 100

Answer:

Lower limit = 1007.95 cm/s

Upper limit = 1142.05 cm/s

Step-by-step explanation:

We have to calculate a 95% CI with population's standard deviation known.

The sample is size n=60, with mean M=1075.

The confidence interval can be expressed as:

$M-z*\sigma/\sqrt{n} \leq\mu\leq M+z*\sigma/\sqrt{n}$

For a 95% CI, the value of z=1.96.

$1075-1.96*265/\sqrt{60} \leq\mu\leq 1075+1.96*265/\sqrt{60} \\\\1075-67.05 \leq\mu\leq 1075+67.05\\\\ 1007.95 \leq\mu\leq 1142.05$
