Answer:

(A)

Step-by-step explanation:

Point A is at (-2,4)

Answer:

$500

Step-by-step explanation:

<h3>Given</h3>

Sofa = s
Love seat = l
Chair = c

Sofa and love seat cost = $1300
Sofa and 2 chairs cost = $1400
Sofa, love seat and one chair cost = $1600

Love seat = ?

<h3>Solution</h3>

<u>Equations as per given are:</u>

s + l = 1300
s + 2c = 1400
s + l + c = 1600

<u>Subtract equation 1 from equation 3:</u>

s + l + c - s - l = 1600 - 1300
c = 300

<u>Considering this in the equation 2:</u>

s + 2*300 = 1400
s = 1400 - 600
s = 800

<u>Substituting s in the equation 1:</u>

800 + l = 1300
l = 1300 - 800
l = 500

<u>Answer:</u> Love seat costs $500

What is the volume of a cylinder with base radius 222 and height 666? either enter an exact answer in terms of \piπpi or use 3.1

Leno4ka [110]

In this question, it is given that the base radius is 2 , height is 6 and the value of pi is 3.14 .

And we have to find the volume of the cylinder, and for that, we have to use the following formula

$V = \pi r^2 h$

Substituting the values of pi,r and h, we will get

$V = 3.14(2)^2 * 6 = 75.36 \ cubic \ units$
