The formula to solve a cylinder is V=πr²h

So, round pi to 3.14

We must plug in for the radius (r) in this equation. To do this, we must half up the diameter, 5. 5/2 = 2.5

6 is height

V=3.14 * 2.5² * 6

V=117.81 we must round though to tenth, and that would be:

Answer V=117.8m³

The length of a rectangle is 3 more than 4timesthe width . If the length of the rectangle is 27 feet what is the width

vlabodo [156]

To answer this question, you need to translate the description into a formula. The formula that can be made should be: length of rectangle= 3+ (4* rectangle width). You already know the length, so you can find the width by inserting it to the formula. The calculation would be:

Length= 3+ 4*width
27ft= 3ft+ 4*width
4*width= 27ft-3ft= 24ft
width= 6ft

you measure the period of a mass oscillating on a vertical spring ten times as follows: period (s): 0.96, 1.40, 1.57, 1.25, 1.16

Law Incorporation [45]

For the given sample, mean = 1.307 and standard deviation = 0.1865.

Given,

Sample

xi : 0.96, 1.40, 1.57, 1.25, 1.16, 1.46, 1.44, 1.50, 1.11, 1.22

Total samples N=10

Mean,

$x =$ (∑ $x_{i}$ ) / N

= (0.96 + 1.40 + 1.57 + 1.25 + 1.16 + 1.46 + 1.44 + 1.50 + 1.11 + 1.22) / 10

= 13.07/10

= 1.307

Standard deviation = $\sqrt{}$ ((∑ $x_{i}$ $-x)^{2}$ /N)

Therefore we have to calculate (∑ $x_{i} -x)^{2}$ first.

That is,

(∑ $x_{i} -x)^{2}$

= (0.96 - 1.307)² + (1.40 - 1.307)² + (1.57 - 1.307)² + (1.25 - 1.307)² + (1.16 - 1.307)² + (1.46 - 1.307)² + (1.44 - 1.307)² + (1.50 - 1.307)² + (1.11 - 1.307)² + (1.22 - 1.307)²

= 0.34781

Now standard deviation = √((∑ $x_{i} -x)^{2}$ /N)

= $\sqrt{\frac{0.34781}{10} }$
