Answer and Step-by-step explanation:

The volume of a cylinder is $\pi r^{2} h$ , in which:

r = radius

h = height

d = 2 × r

$\pi$ will equal 3.14.

Plug it in to the equation.

$V = (3.14)(12^{2} )(42)\\\\\\\\V = (3.14)(144)(42)\\\\\\\\V = (452.16)(42)\\\\\\\\V = 18990.72cm^3$

18990.72 $cm^3\\$ is the answer. (2nd Answer choice)

x = -2

Expression is:

$5 - x^2$

Plug -2 in for x.

$5 - (-2)^2\\\\\\\\5 - 4\\\\\\\\1$

1 is the answer choice. (1st Answer choice).

What is the y intercept of the graph of 4x + 2y = 12

yan [13]

Answer:

the y intercept is 6

Step-by-step explanation:

Step 1: Add -4x to both sides.

4x+2y+−4x=12+−4x

2y=−4x+12

Step 2: Divide both sides by 2.

2y /2 = −4x+12 /2

y=−2x+6

Points (3,6)

x intercept is 3 and y intercept is 6
