<span>D = 180 * (n -2)
D = 180n -360
180n = D +360
n = (D / 180) + 2
So, the answer is "A"
And we can test this with a square, sum of angles = 360
n = (D / 180) +2
n = (360 / 180) +2
number of sides = 4
correct

Given that the mean is 55 inches and Dave is 57 inches, he would have increased the mean of the height in the stem-and-leaf plot that the students were making. This is however is also dependent upon the central tendency that was used, in this case the central tendency is mean or average.
The answer is the test contains 10 3pt questions and 14 5 pt questions. Any questions please just ask!!! thank you!
Answer:
360°
Step-by-step explanation:
From the figure attached,
R, S, T and Q are the points on a circle O.
Since, "measure of an arc of a circle is equal to the measure of the angle subtended by the arc at the center."
By this statement,



m(major arc RQ) = m(∠QOR)
Now
+ m(major arc RQ) = 
Since sum of all angles at a point = 360°
+ m(major arc RQ) = 360°
The volume formula of a cone is

the r is the radius and h is the height. However, if you multiply by pi, you will get an approximated volume of the cone. So we will multiply like this for now.

Don't worry, we'll use pi in the end.
I'm going to assume that 7 inches is your radius. We need to plug in 7 for r and 4 in for h into the equation. Once we do that, it will look like this.


means we will need to divide one by 3. That gives us 0.33333... now we have to multiply by

we get 16.33333... now the last thing we need to do is multiply by 4, which is h. We get 65.33333. Add pi and you have your answer.
