Answer:

Option B. 58.08π m³

Step-by-step explanation:

We have to find the volume of the cylinder in terms of π.

Radius of the cylinder is r = 2.2 m and height = 12 m

Now we know the formula of volume of the cylinder

V = πr²h

V = π (2.2)²(12)

V = 58.08π m³

Therefore, volume of the given cylinder is 58.08 m³.

Option B. 58.08π is the correct option.

160 bananas; 20% decrease
Kay [80]
First you turn 20% into a decimal by dividing by 100 and you get .20
then you multiply .20 by 160 and get 32
then subtract:
160-32=128
So if you have 120 bananas and you have a 20% decrease then you would have 128 left over

Hope this helped!! :D

1.Encuentra la ecuación de la circunferencia que tiene como ecuación ordinaria (x-4)² + (y+5)²= 25 2- encuentra la ecuación gene
rodikova [14]

Responder:

1) x² + y²-8x + 10y + 16 = 0

2) x² + y² + x + 18y + 33 = 0

Explicación paso a paso:

A partir de la pregunta, debemos expresar la ecuación en la forma estándar de un círculo expresado como;

x² + y² + 2gx + 2fy + c = 0 donde;

(-g, -f) es el centro.

1) Para la ecuación (x-4) ² + (y + 5) ² = 25

Expande el paréntesis;

(x-4) ² + (y + 5) ² = 25

x²-8x + 16 + y² + 10x + 25 = 25

x²-8x + 16 + y² + 10y + 25-25 = 0

Recopile términos similares;

x² + y²-8x + 10y + 16 + 0 = 0

<em>x² + y²-8x + 10y + 16 = 0 </em>

<em>Por lo tanto, la ecuación requerida es x² + y²-8x + 10y + 16 = 0 </em>

<em> </em>

2) Para la expresión (x + 1) ² + (y + 9) ² = 49

x² + x + 1 + y² + 18y + 81 = 49

x² + x + 1 + y² + 18y + 81-49 = 0

Recopile términos similares;

x² + y² + x + 18y + 82-49 = 0

<em>x² + y² + x + 18y + 33 = 0 </em>

<em>Por tanto, la ecuación requerida es x² + y² + x + 18y + 33 = 0</em>
