The common ratio is the current number divided by the previous. So the ratio is 1/2

The sequence is 12, 6, 3, 3/2, 3/4 ...

You can obtain any number multiplying the previous number times 1/2.

6 = 12 *(1/2)

3 = 6*(1/2)

3/2 = 3*(1/2)

Answer:

Common ratio = \frac{1}{2}

Step-by-step explanation:

A sequence that progresses geometrically has the first term as 12.

Each number is the previous number divided by 2.

so the sequence will be 12, 6, 3, 1.5...........

Explicit formula of a geometric sequence is given by

T_{n}=a(r)^{n-1}

Where T_{n} = nth term of the sequence

a = first term

r = common ratio

and n = number of term

In this sequence common ratio = \frac{\text{Successive term}}{\text{previous term}}

= \frac{6}{12}

= \frac{1}{2}

Therefore, common ratio will be \frac{1}{2}

Hey love! <3

Answer:

The right answer is A = 49.6 π ft^2

Step-by-step explanation:

<em><u>(Let pi = 3.1415926535898)</u></em>

<em>The formula for calculating the surface area of a cylinder is A=2πrh+2πr^2</em>

<em>So if r = 4 ft</em>

<em>and h = 2.2 ft</em>

<em>A= 2π(4)(2.2)+2π(4)^2</em>

<em>Once we've plugged in our formulas our final surface area is A =</em><em> 49.6 π ft2</em>

<em />

<em>Hope this helped you calculate the surface area! ◃┆◉◡◉┆▷ Sincerely, Kelsey from Brainly.</em>
