Triangle PQR has the following coordinates P(2,4), Q(4,4) and R(4,2). Using a scale of 1cm to represent 1 unit on each axis, enlarge PQR using a scale factor (k) of -1.5 at the center (-1,-2). Please do it on a graph

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

the translated point is (5,2)
