In a plan for area codes, the first digit could be any number from 2 through 8, the second digit was either 0 or 3, and the third digit could be any number except 0. With this plan, how many different area codes were possible?

you have to put the graph on here with the question

the distributive property states that:

then, when applying the property we have to multiply the -2 for each term within the parenthesis:

okay..i will pick 8!

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
