Answer:

339.24

Step-by-step explanation:

To find the surface area, you will need to the the area of the base of the cylinder. To do that, use the formula A=pi (r)^2

The radius is half the diameter do r=3

3.14(3)^2 should give you about 28.27.

This is the area of the top and bottom of the cylinder.

Now, do 28.27x10=282.7 to find the height surface area.

282.7+28.27+28.27=Surface area.

SA= about 339.24

The variables x and y are related proportionally. When x = 4, y = 14. Find y when x = 40.

vichka [17]

Answer:

See Below

Step-by-step explanation:

Take the the given information and compare to the question being asked

$\frac{y}{x}$ . So insert the x & y's of both equations (ima do y over x to make it easier)

$\frac{14}{4} =\frac{y}{40}$

divide 14/4

3.5 = $\frac{y}{40}$

then multiply both sides by 40 to isolate y

140 = y

Check by reinserting 140 and divide it by 40

The equation y minus 1 = negative 7 (x minus 3). is written in point-slope form. What is the y-intercept of the line?

Tresset [83]

Answer:

(0, 22)

Step-by-step explanation:

So you have the equation:

$y-1=-7(x-3)$

So first let's define what the "y-intercept" is. The y-intercept, of a line is like the name implies, when the line intercepts or "passes" the y-axis. And if you were to take any point on the y-axis, the y-value may vary, but there is one value that doesn't change, and that's the x-value. the x-value is always going to be zero, no matter where you are on the y-axis. So to find the y-intercept simple plug 0 in as x. This gives you the equation:
