The cylinder is 20cm high and radius of its circular face is 3cm What is the total perimeter and area of the whole net?

trasher [3.6K]

Answer: $52\ cm,\ 176.55\ cm^2$

Step-by-step explanation:

Given

The cylinder is 20 cm high

The radius of the cylinder is $r=3\ cm$

The total area of the figure is the sum of the rectangle and two circles

$\Rightarrow \text{Perimeter P=}2[h+2r]\\\Rightarrow P=2[20+6]\\\Rightarrow P=52\ cm$

The total area of the figure is

$\Rightarrow \text{Area A=}h\times 2r+2\pi r^2\\\Rightarrow A=20\times 6+2\times \pi \times 3^2\\\Rightarrow A=120+18\pi\\\Rightarrow A=176.55\ cm^2$

When the polynomial is written in standard form, what are the values of the leading coefficeient and the constant? 5x + 2 - 3x2

Elina [12.6K]

Answer:

The leading coefficient is -3

The constant is 2

Step-by-step explanation:

The standard form of a polynomial is the descending order, that means that it must be written according from its higher power, down straight to the coefficient with no variable.

Hence, the leading coefficient is the one that is next to the highest exponent of the polynomial, in this case: =3x2.

The second term is 5x

And the last is 2. the constant

A club is selling hats and jackets as a fundraiser. Their budget is $1500, and they want toorder at least 250 items. Each hat co

Tom [10]

Let H be the number hats and J the number of jackets. Then, we can write,

$5H+8J\le1500$

Now, since they want 250 items at least, we can write

$H+J\le250$

Hence, the system of inequalities is

$\begin{gathered} 5H+8J\le1500 \\ H+J\le250 \end{gathered}$
