On a coordinate grid, both point (−4, −1) and (2, 6) point are reflected across the y-axis. what are the coordinates of the reflected points?
(4, 1) and (−2, −6)
(−4, 1) and (−2, 6)
(−4, 1) and (2, −6)
(4, −1) and (−2, 6)

for this case we have that by definition, the surface area of a cylinder is given by:

where:

r: it is the radius of the cylinder

h: it is the height of the cylinder

we can also rewrite it as:

where:

la: it's the lateral area

ba: area of the base
