Step-by-step explanation:
With the given information, use the point-slope formula to write the equation of the line. Substitute values for the
,
, and
to find the answer.
represents the slope, so substitute -5 in its place. The
and
represent the x and y values of one point the line intersects, so substitute 4 for
and -6 for
. This gives the following equation:
Answer:
the volume of the pipe is 649.98 cubic inches.
Step-by-step explanation:
We have been given that a collar of Styrofoam is made to insulate a pipe. We are asked to find the volume of the given pipe.
We will use volume of hollow cylinder formula to solve our given problem.
where,
R = Radius of external cylinder,
r = Radius of internal cylinder.
h = Height of cylinder.
substituting our given values in above formula, we will get:
Therefore, the volume of the pipe is 649.98 cubic inches.
