Answer:

The volume of the cylinder would be 226.19in however if you need it in terms of pi it would be V = 72 π in3

Step-by-step explanation:

V=πr2h=π·62·2≈226.19467, hope I was able to help you

And that is basically what you have to do

Answer:

72π inches^3

Step-by-step explanation:

The volume of a cylinder can be found using:

v=πr^2h

We know that the radius is 6 inches, and the height is 2 inches. So, we can substitute 6 in for r, and 2 in for h.

v= π 6^2 *2

Evaluate the exponent

v= π 36*2

Multiply 36 and 2

v= π72

So, the volume in terms of pi is:

72π inches^3

You asked your classmates to name their favorite type of music. You found that 12 students like rock, 8 like rap, 6 like R&B

ale4655 [162]

From this, we can see that the total amount of students being asked = 12 + 8 + 6 + 4 = 30.

12 of 30 like rock, in percentages that is 12/30 = 40$

Full circle has 360 degrees.

40% * 360 degrees = 144 degrees

144 degrees should represent rock music on a pie chart.

Hope this helps!

Angles α and β are angles in standard position such that: α terminates in Quadrant II and sinα = 3/5, β terminates in Quadrant I

777dan777 [17]

We are given

Angles α and β are angles in standard position

and

α terminates in Quadrant II

β terminates in Quadrant I

and we have

$sin(\alpha)=\frac{3}{5}$

we can use triangle and find cos(α)

we get

$cos(\alpha)=-\frac{4}{5}$

and we have

$cos(\beta)=\frac{4}{5}$

we can draw triangle

$sin(\beta)=\frac{3}{5}$

now, we can use formula

$cos(\alpha+\beta)=cos(\alpha)cos(\beta)-sin(\alpha)sin(\beta)$

now, we can plug values

$cos(\alpha+\beta)=-\frac{4}{5}\times \frac{4}{5}-\frac{3}{5}\times \frac{3}{5}$

now, we can simplify it

$cos(\alpha+\beta)=-\frac{16}{25}-\frac{9}{25}$

$cos(\alpha+\beta)=-\frac{(16+9)}{25}$

$cos(\alpha+\beta)=-\frac{25}{25}$

$cos(\alpha+\beta)=-1$ ...............Answer

If y = -7x 3 what is the value of y when x = -1

Len [333]

You would do... 7*-1*3 (* is times) And that is -21.
So y = -21
