Write a polynomial of least degree with roots 9 and -3

  y = x^2 -6x -27

Step-by-step explanation:

When "a" is a root, (x-a) is a factor. The minimum polynomial with the listed roots will be ...

  y = (x -9)(x +3)

  y = x^2 -6x -27

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
