Can someone help me with these questions

Answer:

1.) can not be found

2.)V=11403.98

3.)

Step-by-step explanation:

volume = π r×r × H

r = Radius

H = height

π = 3.14

the first one does not have a radius so therefore we can NOT find the volume

the second one is π×(11×11) ×30 =11403.98

the 3rd one is π× (10×10) ×5 =1570.79

hope this helped

Find the slope of the line that passes through the points (0, -3) and (-4,1).

kozerog [31]

The formula for slope is $\frac{y_{2} -y_{1} }{x_{2} -x_{1} }$

In this case:

$y_{2} = 1\\ y_{1} }= -3\\x_{2} = -4\\x_{1} = 0$

so...

$\frac{1 - (-3)}{-4 - 0}$

$\frac{4}{-4}$

-1 <<<The slope

Hope this helped!
