Find the mean, variance, and standard deviation of the sample with

azamat

Mean:-

$\\ \tt\hookrightarrow \dfrac{\sum x}{n}=\dfrac{210}{10}=21$

Standard Deviation:-

$\\ \tt\hookrightarrow \sqrt{\dfrac{\sum x^2}{n}-(\sum x/n)^2}$

$\\ \tt\hookrightarrow \sqrt{\dfrac{5006}{10}-(21)^2}$

$\\ \tt\hookrightarrow \sqrt{500.6-441}$

$\\ \tt\hookrightarrow \sqrt{59.6}$

$\\ \tt\hookrightarrow 7.72$

Variance:-

$\\ \tt\hookrightarrow (S. D)^2=(7.72)^2=59.6$

The correct answer to the exercise is:

Surface area of a circle = 633.1 $mm^{2}$

Step-by-step explanation:

To obtain the surface area of a circle, you can use the formula:

Surface area of a circle = π * $r^{2}$

Where:

π = 3.14 (the exercise give this)
r = Circle radius.

How you can see, in the picture gives you a straight line that passes through the circle side by side, the circle radius is half of that value, then:

r = 28.4 mm / 2
r = 14.2 mm

Now, we can replace the values in the first formula:

Surface area of a circle = π * $r^{2}$

Surface area of a circle = 3.14 * $(14.2 mm) ^{2}$

Surface area of a circle = 3.14 * 201.64 $mm^{2}$

Surface area of a circle = 633.1496 $mm^{2}$

Surface area of a circle = 633.1 $mm^{2}$ (rounded to the nearest tenth).
