Lucy wants to decorate the curved surface of a trash can that has a radius of 4 in. and a height of 12 in. What is the area of the curved surface of the trash can she will need to decorate?

A trash can with radius 4 inches and height 12 inches.

This is probably 95% wrong but 48?

option a.

step-by-step explanation:

if you look closely at the graph, we can notice that the function is not defined at two different points.

if you look at functions b and c, you will notice that both functions are not defined at just one point. the function b is not defined at x= -5/2 and function c is not defined at x=-5. both options are discarded, given that our function should not be defined at two fiferent points.

now, if you look closely at the graph you will notice that the function sketched is not defined at x=5 and x=-2.
