The formula of a surface area of a cylinder:

$S.A.=2\pi r^2+2\pi rH$

r - radius

H - height

We have:

r = 5 in

H = 4 in

Substitute:

$S.A.=2\pi(5^2)+2\pi(5)(4)=2\pi(25)+2\pi(20)\\\\=50\pi+40\pi=90\pi\ in^2$

$\pi\approx\dfrac{22}{7}$

Substitute:

$S.A.\approx90\cdot\dfrac{22}{7}=\dfrac{1980}{7}\approx282.857\ in^2$

sampling method: assume that the population consists of all students currently in your statistics class. describe how to obtain

Naddik [55]

To obtain the sample, one can choose the names of 6 students out of a hat from the students in the class using random sampling.

<h3>What is random sampling?</h3>

It should be noted that a simple random sample is a subset of a statistical population where each member of the subset has an equal probability of being chosen.

Systematic sampling is when the sample members from a larger population are selected based on a fixed, periodic interval. If you want to select a random group of 6 students from a population of about 60 using systematic sampling, every 10th person on the list is selected.

You are buying an area rug for your bedroom. The area of your room you want to cover is 40 feet squared. You find that the lengt

Kamila [148]

The length and the width of the rug having an area of 40 square feet will be 5 feet and 8 feet respectively.

Area is defined as the space covered by any object in the two dimensional plane. Here it is given that the area of the rug should be 40 square feet and the length of the rug is 3 less then its width.

So to find out the length and the width we will form an equation.

Let the width is = x feet

So the length will be = x-3 feet

Now the area will be

$x(x-3)=40$
