Answer:

D: 109 cm

Step-by-step explanation:

The formula of circumference is

\pi d

Diameter =

17.4 \times 2 = 34.8

Hence, circumference =

34.8 \times \pi = 109.32742...

rounded of to 109.

Answer:

circumference of a circle = 109.272

so correct option is D. 109 cm

Step-by-step explanation:

given data

circle radius = 17.4 cm

to find out

What is the circumference of the circle

solution

we will apply here formula for the circumference of a circle that is express as

circumference of a circle = π × d    .........................1

here d is diameter of circle

and we know diameter = 2 × radius

put her value of radius we get diameter

so diameter d = 2 × 17.4 cm

diameter d = 34.8 cm

put these value in equation 1 we get

circumference of a circle = 3.14 × 34.8

circumference of a circle = 109.272

so correct option is D. 109 cm

RoseWind [281]

Answer:

  6/(49π) ≈ 0.03898 m/min

Step-by-step explanation:

  V = πr²h . . . . formula for the volume of a cylinder

  dV/dt = πr²·dh/dt . . . . differentiate to find rate of change

Solving for dh/dt and filling in the numbers, we have ...

  dh/dt = (dV/dt)/(πr²) = (6 m³/min)/(π(7 m)²) = 6/(49π) m/min

  dh/dt ≈ 0.03898 m/min

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.
