Answer:

The formula of the volume of a cylinder is known as follow

Where

π is 3,14 or 22/7.

d (diameter) is a straight line segment that crosses a center and connects two points on the circle.

r is the radius of the to part of the cylinder.

h is the height.

we can subsitute to our formula knowing that

d = 4cm (turn to r = <em>2cm</em>,because the formula use r) ; h = 11cm

V = πr²h

= 3,14 × 2² × 11

= 3,14 × 4 × 11

= 3,14 × 44

= 138,16 rounded off (138,2cm3) result

Find the line parallel to the line y=3x+5 which passes through the point (1,4). a. y=-1/3x+1 b. y=-3x+1 c. y=1/3x+1 d. y=3x+1

Vladimir [108]

Answer:

Step-by-step explanation:

So we want to find the equation of the line parallel to y=3x+5 and goes through the point (1,4).

First, since the new line is parallel, its slope must be equivalent. Therefore, the slope of our new line <em>must</em> also be 3.

Now, we can figure out the rest of the equation using the point-slope form:

$y-y_1=m(x-x_1)$

Substitute 3 for m. Let's let (1,4) be x₁ and y₁. Thus:

$y-4=3(x-1)$

Distribute the right:

$y-4=3x-3$

Add 4 to both sides:

$y=3x+1$

And we're done!

The correct answer is D.
