Answer:
5889.95
Step-by-step explanation:
volume of a cylinder is the area of the base times the height. To find the area of the base it is Since they give diameter you need to find radius by dividing. 17.5 divided by 2 is 8.75. the area is
then times height it is
then, like they said, use 3.14 as pi. Round to get 5889.95 :)

Answer:
y=[-4]x+[10]
Step-by-step explanation:
For a line to be perpendicular to another it must have the reverse reciprocal of the opposite line, to find the reverse reciprocal you take your slope, flip the numerator and denominator, and multiply it by -1.
The slope turns into
and is then multiplied by -1 to become
which can be simplified down to:
Now that we know the slope we need the line to pass through a point, so we will use point slope form:
Substitute in our slope and point values:
Now solve for y:
Then you will find that line runs perpendicular to
and intersects point (2,2).
