How many solutions does the system have?

by substituting we get,

x² = 0

x = 0

hence, we just have one solution

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
