Answer:

V = 77 m^3

Step-by-step explanation:

We want the volume of the cylinder

V = pi r^2 h

We know the diameter not the radius

r = d/2 = 7/2 = 3.5

V = 3.14 * (3.5)^2 (2)

V = 76.93 m^3

To the nearest cubic meter

V = 77 m^3

What is the solution to the system of equations? -2x + y = -5 3x – 2y = 12 A) (3, 1) B) (6, 3) C) (-2, -9) D) (-2, -1)

max2010maxim [7]

Answer:

The correct answer is D) (-2, -1)

Step-by-step explanation:

In order to solve this system of equations, start by multiplying the entire first equation by 2. Then add the two equations together. This will get the y's to cancel and allow you to solve for x.

-4x + 2y = -10

3x - 2y = 12

---------------------

-x = 2

x = -2

Now that we have the value for x, we can find y by plugging the x value into either equation.

-2x + y = -5

-2(2) + y = -5

-4 + y = -5

y = -1
