To practice writing the equations of horizontal parabolas, write the equations of these two parabolas in vertex form: focus at (4, 3), and directrix x = 2
focus at (2, -1), and directrix x = 8

(The other info is in my other questions)

i think the length is 12 and the width is 17

2, 2, 2 or -4, 20, 29

step-by-step explanation:

there is two ways you can do it.

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d
