Answer:

Step-by-step explanation:

for the cylinder

27π = πr²h = πr²(2r) = 2πr³

for the sphere

V = (4/3)πr² = (2/3)(2πr³) = (2/3)27π

Please help i dont know how to do this

Hello once again!

When you see a question like this, you need to find the equation of the straight line.

The formular used is y = mx + c
Where
m = slope
c = constant

First find the slope, since it's a straight line, any 2 coordinates can be used.

m = { \frac{y_1 - y_2}{x_1-x_2} } \\ m= { \frac{16 - (- 8)}{-2 - 2} } \\ m= { \frac{24}{-4} } \\ m = -6

Now we need to substitude in the slope, and one of the coordinate you used to find the slope, to the formular to find the constant.

In this case i'm using the coordinate
(-2, 16)

y = mx + c
16 = -6(-2) + c
16 = 12 + c
c = 4

∴ The equation of the line is y = -6x + 4

The next step is to simply substitude in the x = 8 to the equation to find y.

y = -6(8) + 4
y = -48 + 4
y = -44

there are 48 students in a school play. the ratio of boys to girls is 5:7. how many more girls than boys are in the school play?
Alex Ar [27]
We can use trial or error method here...

If we take 4 table, 4*5 = 20 and 4*7 = 28. 20+28 = 48.
20 : 28 = 5 : 7

So, there are 20 boys and 28 girls in a school play and there are 8 girls more than boys.

If you look over tables and try it out, only 4 table works for the given ratio.

Find the equation of the line through point (-5,5) and perpendicular to y = 5/9x - 4
tankabanditka [31]

Answer:

9x+5y=-20

Step-by-step explanation:

y = \frac{5}{9} x - 4

compare with that y=mx+c

where m=slope .

So after comparing we get m=\frac{5}{9}

As the lines are perpendicular

m1*m2=\ -1

m2 \ =\ \frac{-1}{m1}

therefore m2=\frac{-9}{5}

Now from the equation

y - b = m(x - a ) this equation passing to the point (-5,5) with m=\frac{-9}{5}

y-5=\frac{-9}{5} (x+5)\\5y-25=-9x\ -45\\9x+5y=-20

Therefore equation is

9x+5y=-20

Find the area of the circle with the given radius or diameter use pi equals 3.1 4 R is equal to six
marysya [2.9K]
<h2>Hello!</h2>

The answer is:

The area is equal to 113.04 units.

<h2>Why?</h2>

To find the area of the circle, we need to use the given information about the radius (6).

So, the area of a circle is given by the following formula:

A=\pi *r^{2}

Where,

\pi=3.14 (For This Case)\\r=radius

Substituting the given radius, we have:

A=3.14*(6)^{2}=3.14*36=113.04units

Have a nice day!
