1
Recognize and use volume in solving multistep problems
Example
Note: Figure not drawn to scale.The figure above shows a right circular cylindrical wheel of cheese
inches high from which a wedge weighing
pound has been cut. All cuts are perpendicular to the base and radiate from points
and
, the centers of the circular top and bottom. What is the weight, in pounds, of the original uncut wheel? -
2
Use the relationships between the slopes of parallel and perpendicular lines in the coordinate plane
ExampleIn the
plane, the slope of line
is
and its
is
. What is the equation of the line perpendicular to
that intersects
at its
?
Skills needed to score in the next band
