7x-3y=-7 slope of line perpendicular

kap26 [50]

Answer: -3/7

Step-by-step explanation:

The first step is to find the slope of the line

y = mx + c where m is the slope of the line
Rearrange the equation and we get

3y = 7x + 7
y = 7x/3 + 7/3

So the slope of the line 7x - 3y = -7 is 7/3

There is another rule that states: The product of the slopes of two lines perpendicular to each other is -1

So, the slope of the line perpendicular to 7x - 3y = -7 is -1/(7/3) = -3/7

Find the volume of the cylinder please help show work

Alinara [238K]

3.
$v = \pi {r}^{2} h$
the volume equation for cylinder
$v = \pi {6}^{2} (12) \\ v = \pi36(12) \\ v = 432\pi \\ v = 1357.16$
5. diameter =half of radius
$v = \pi { 27.2}^{2} (15) \\ v = \pi295.24(15) \\ v = 4437.6\pi \\ v = 13941.13$
