Given the following geometric sequence, find the common ratio: {225, 45, 9...}

Tom [10]

Answer:

$\frac{1}{5}$ is the common ratio

Step-by-step explanation:

Common ratio(r) states that the ratio of each term of a geometric sequence to the term preceding it.

$r = \frac{a_2}{a_1} =\frac{a_3}{a_2}........\frac{a_{n+1}}{a_n}$

Given the sequence:

225, 45, 9, .........

Here,

$a_1 = 225$

$a_2 = 45$

$a_3 = 9$ and so on...

Using definition to find r.

$r = \frac{45}{225}=\frac{9}{45}......$

After solving we get;

$r = \frac{1}{5}$

Therefore, the common ratio is, $\frac{1}{5}$

Which container holds the most?

goldenfox [79]

Cylinder:

V = pi * r^2 * h

V = 3.14 * 9^2 * 11

Simplify exponent:

V = 3.14 * 81 * 11

Multiply:

V = 2797.74

Sphere:

V = 4/3 * pi * r^3

V = 4/3 * 3.14 * 9^3

Simplify exponent:

V = 4/3 * 3.14 * 729

Multiply:

V = 3052.08

Cone:

V = 1/3 * pi * r^2 * h

V = 1/3 * 3.14 * 12^2 * 20

Simplify exponent:

V = 1/3 * 3.14 * 144 * 20

Multiply:

V = 3014.4

So the Sphere holds the most.
