What’s the height of the can?

5 inches

Step-by-step explanation:

The formula to find the surface area of a cylinder is A = 2πrh + 2πr²  

Since we need the height we will need to solve for h

First we can subtract 2πr² from both sides to get A - 2πr² = 2πrh Then we can divide both sides by 2πr to get

Now we can plug in our known values and solve for h

Here we were given the diameter, d, however this formula is in terms of the radius, r. The diameter is equivalent to double the radius, d = 2r Therefore the radius is equivalent to half the diameter, Plugging in d to solve for r we get which simplifies to r = 1

The two variables for this equation we have no obtained, A = 12π and r = 1, so we can plug them into our equation to solve for the height

The height is 5 inches

Does the problem say y=x+4?
