A cone and cylinder have the same height and the same base radius. If the volume of the cylinder is 81 cm^3 what is the volume of the cone in cm^3?A) 9
B) 27
C) 78
D)243

Answers

Answer:

The volume of the cone is $27cm^3$

Step-by-step explanation:

We know that formulas

Volume of cylinder is

$V_1=\pi r^2 h$

Volume of cone is

$V_2=(1)/(3)\pi r^2 h$

we are given

A cone and cylinder have the same height and the same base radius

So, both will have same radius and height

now, we can find ratios

$(V_2)/(V_1)=((1)/(3)\pi r^2h )/(\pi r^2h)$

now, we can simplify it

$(V_2)/(V_1)=(1)/(3)$

we are given

the volume of the cylinder is 81 cm^3

so, $V_1=81$

now, we can plug it and solve for V2

$(V_2)/(81)=(1)/(3)$

$81* (V_2)/(81)=81*(1)/(3)$

$V_2=27$

So, the volume of the cone is $27cm^3$

HELP PLEASE in two or more complete sentences, describe how to graph the following equation.In your description, include the slope and both the - and -intercepts of the line. y =2

Answers

The method to graph the equation of line is given as below.

What is the Equation of the line in Slope-Intercept form?

Equation of a line in slope-intercept form is y = mx + b, where m is the slope of the line and b is the y-intercept, which is the y-coordinate of the point where it touches the y-axis.

y = 2

Slope intercept form of the line is y = 0x + 2

That is, slope is 0.

Slope is the tangent of the angle that the line makes with the x-axis.

Since, slope is 0, tan (angle) = 0, then the angle making with x-axis = 0

So the line y = 2 will be a line parallel to the x-axis passing through the point y = 2.

The line will not touch the x-axis, so no x-intercept and y-intercept = 2.

Hence, the graph of the line is described.

Answer:

Step-by-step explanation:

Graphing the equation y = 2 is straightforward because it represents a horizontal line. The slope of this line is zero because it doesn't have a changing y-value for any x-value. To graph it, you can draw a horizontal line that crosses the y-axis at y = 2. There are no x-intercepts because the line never crosses the x-axis since it's parallel to it. So, the graph is a straight horizontal line that intersects the y-axis at (0, 2).

Write an equation of a line that is perpendicular to the line below and passes through the given point

Answers

a line perpendicular would have the opposite slope, meaning that if you multilied the line of this slope and the new slope, you would get -1

in y=mx+b m=slope and b=yintercept
-1/5 times 5/1=-1 so the new slope is 5
so y=-1/5x+3
the point you want is 2,8 or this equation is true when x=2 and y=8 are true so subsitute and solve for the new 'b'

8=5(2)+b
8=10+b
subtract 10 from both sides
-2=b

the equaqtion is y=5x-2

When you see an equation in the format:
y = mx + c.
Know that the slope = m.

y = -1/5 x + 3.

Therefore slope, m = -1/5. But for the new line to be perpendicular to this, the new line's slope would be the negative reciprocal of -1/5.

That is using the condition for perpendicularity:
m1* m2 = -1. m1 = -1/5.

Where m2 = new slope of the line.

m2 = -1 / (-1/5) = 5.

So the slope of the perpendicular line is 5.

Using the slope and one point format:

y - y1 = m(x - x1) here (x1 , y1) is the point given (2, 8), x1 = 2 , y1 = 8.

m = 5, the new gradient here.

y - 8 = 5(x - 2)
y - 8 = 5x - 10
y = 5x - 10 + 8
y = 5x -2.

So that's the equation of the perpendicular line passing through the given point.
