Answer:
The cylinder's height is 14 cm
Step-by-step explanation:
Recall that the formula for the volume of a cylinder is given by:
where R is the radius of the cylinder's base, and H the cylinder's height (which we we don't know and need to find)
In order to use this formula to solve for our unknown we need to obtain the radius "R" by using the second piece of information on the length of the base's circumference (22 cm). Recall the formula for the length of a circumference of radius R:
Then, in our case:
We now use this information in the volume equation to find the cylinder's height:

Notice that every pair of point (x, y) in the original picture, has become (-y, -x) in the transformed figure.
Let ABC be first transformed onto A"B"C" by a 90° clockwise rotation.
Notice that B(4, 1) is mapped onto B''(1, -4). So the rule mapping ABC to A"B"C" is (x, y)→(y, -x)
so we are very close to (-y, -x).
The transformation that maps (y, -x) to (-y, -x) is a reflection with respect to the y-axis. Notice that the 2. coordinate is same, but the first coordinates are opposite.
