Answer:

a) 0

b) -1/3

Step-by-step explanation:

It is y2-y1 over x2-x1 that is why you are messing up on your calculation

8+12/17-17 = 0

1+2/-3-6

= -3/9

=-1/3

A cylinder has a radius of 4.5 inches and a height of 12 inches. What is the volume of the cylinder? Use 3.14 for π and round yo

andrey2020 [161]

Answer:

The correct answer is option (A) 763 in³.

Step-by-step explanation:

As per given question we have provided that :

$\red\star$ Radius of cylinder = 4.5 in
$\red\star$ Height of cylinder = 12 in

Here's the required formula to find the volume of cylinder :

$\longrightarrow{\pmb{\sf{V_{(Cylinder)} = \pi{r}^{2}h}}}$

$\pink\star$ V = Volume
$\pink\star$ π = 3.14
$\pink\star$ r = radius
$\pink\star$ h = height

Substituting all the given values in the formula to find the volume of cylinder :

$\longrightarrow{\sf{Volume_{(Cylinder)} = \pi{r}^{2}h}}$

$\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14{(4.5)}^{2}12}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14{(4.5 \times 4.5)}12}}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14(20.25)12}}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} = 3.14 \times 20.25 \times 12}}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} \approx 63.58\times 12}}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} \approx 762.96}}}$

${\longrightarrow{\sf{Volume_{(Cylinder)} \approx 763 }}}$

$\star{\underline{\boxed{\sf{\red{Volume_{(Cylinder)} \approx 763 \: {in}^{3}}}}}}$

Hence, the volume of cylinder is 763 in³.

What is a polynomial ?

ikadub [295]

aApolynomial is an expression consisting of variables and coefficients, that involves only the operations of addition, subtraction, multiplication, and non-negative integer exponents of variables.

There are 3 sets of polynomials; LINEAR, QUADRATIC and CUBIC

Linear: $ax + b = 0$

Quadratic: $ax^2+bx+c=0$

Cubic: $ax^3 + bx^2+cx+d = 0$

The volume of a rectangular prism is 960 cubic inches. If the dimensions of the base are doubled and the height remains the same

Furkat [3]

Answer:

3840 cubic inches

Step-by-step explanation:

The volume of a rectangular prism is 960 cubic inches

Let the dimensions be lXwXh,

l=length of the base

w=width of the base

h=height of the base

The volume, lwh=960 cubic inches

If the dimensions of the base are doubled and the height remains the same

Volume of the new rectangular prism=2l X 2w X h =4lwh

=4 X 960 =3840 cubic inches
