The cylinders are similar. The volume of the larger cylinder is 9648 cubic inches. What is the volume of the smaller cylinder?

zalisa [80]

Hey there :)

The volume formula of a cylinder is:
V = $\pi$ r²h

The volume of the larger volume is given to be 9648³ and the height is 18 in
We need to find the radius first

9648 = $\pi$ r²(18)
$\frac{9648}{18}$ = $\pi$ r²
536 = $\pi$ r²
$\frac{536}{ \pi}$ = r²
$\sqrt{ \frac{536}{ \pi } }$ = r
r ≈ 13.06

The ratio of the big cylinder to small cylinder is:
18 : 9 (given height)
So the big cylinder is 2 times bigger than the small cylinder
Therefore the radius of the big cylinder is as well 2 times bigger

$\frac{13.06}{2} = r$
r ≈ 6.53 ( the radius of the small radius )

V (of small cylinder) = $\pi$ (6.53)²(9)
= 1206 in³

First: State the degree and tell which monomial (term) you determined to be the one as the greatest degree. Second: Classify eac

kobusy [5.1K]

Answer:

$1.\text{ }7x^4+5x^2+x-9$

The term with the greatest degree is $7x^4$

The polynomial has degree 4 and is classified as a quadratic polynomial of 4 terms.

$2.\text{ }7x^6-4x^3+1/x$

It is not a polynomial.

Explanation:

<em>Polynomials</em> are expressions with terms composed of <em>monomials</em>.

A <em>monomial</em> is an expression formed by the product of a coefficient (constant numbers, like 3, 4/5, or even a root), and a literal part.

The literal part may consist of one or more letters and each letter may be raised to a non-negative integer number (positive or zero).

Hence, for instance, (2/9)x²y⁵z⁴³ is a monomial.

The given expressions are:

$1.\text{ }7x^4+5x^2+x-9$

$2.\text{ }7x^6-4x^3+1/x$

$1.\text{ }7x^4+5x^2+x-9$

This expression is a polynomial formed by <em>4 terms </em>or monomials.

The monomials are:

$7x^4,\\ \\ 5x^2,\\ \\ x,\text{ }and\\ \\ 9$

The degrees of each monomial are:

$7x^4,\text{ }degree\text{ }4\\ \\ 5x^2,\text{ }degree\text{ }2\\ \\ x,\text{ }degree\text{ }1,\text{ }and\\ \\ 9\text{ }degree\text{ }0$

Thus, the one with the <em>greatest degree</em> is $7x^4$ . It defines the degree of the of the polynomial; hence <em>the polynomial has degree four and is classified as quartic polynomial of four terms.</em>

$2.\text{ }7x^6-4x^3+1/x$

This is <em>not a polynomial</em>, because the letter in the last term, i.e. 1/x has a negative power:

$1/x=x^{-1}$

As stated above, the powers have to be positive integers or zero (for the constant term).

Some special names used to classify the polynomials are:

Degree 1 – linear

Degree 2 – quadratic

Degree 3 – cubic

Degree 4 – quartic

Degree 5 – quintic

You can find other classifications in your book or in the internet.

Please please help me out

deff fn [24]

Answer:

x = 60°

Step-by-step explanation:

The measure of x is one- half the difference of the measures of the intercepted arcs.

The minor arc = 120°, hence

The major arc = 360° - 120° - 240°, so

x = 0.5(240 - 120) = 0.5 × 120° = 60°

If 30 is the total number of starbursts in a bag, how many starbursts are 70% of the bag?

daser333 [38]

Ten percent is 3 starburst because to find ten percent you divide the total number by ten. now to find 70 percent you times ten percent by seven. 3 x7 = 21 :)
