Answer:

7/3r

Step-by-step explanation:

To find the simplest form, we must find the relationship between the surface area and volume of a cylinder. The cylinder with radius r and height h has;

surface area = 2πr (r + h)

volume = πr²h

hence the ratio of surface area to volume

= 2πr (r + h) : πr²h

= 2(r + h) = rh

Hence if the height is 6r and the radius is r

The ratio is

= 2(r + 6r) : r(6r)

= 14r : 6r²

= 7:3r

Answer:

ratio of surface area to volume = 7 to ratio 3r

Step-by-step explanation:

The volume of a cylinder = πr²h

Surface area = 2πr(r + h)

where

r = radius

h = height

h = 6r

where

r = radius

volume = πr²h

volume = π × r² × 6r

volume = 6πr³

surface area = 2πr(r + h)

surface area = 2 × π × r (r + 6r)

surface area = 2πr(7r)

surface area = 14πr²

surface area = 14πr²

ratio of surface area to volume = 14πr²/ 6πr³

ratio of surface area to volume = 7/3r

ratio of surface area to volume = 7 to ratio 3r

Question 1 Part B (3 points): Using the GCF that you chose in part A, factor that GCF out of the polynomial:
Aleks [24]

The factor of the polynomial 18x³ + 6x²y - 9x² - 3xy will be 3x(6x² - 2xy - 3x - y). Then the correct option is C.

<h3>What is a factorization?</h3>

It is a method for dividing a polynomial into pieces that will be multiplied together. At this moment, the polynomial's value will be zero.

The polynomial is given below.

⇒ 18x³ + 6x²y - 9x² - 3xy

Then the factor of the polynomial will be

⇒ 18x³ + 6x²y - 9x² - 3xy

⇒ 3x(6x² - 2xy - 3x - y)

More about the factorization link is given below.
