Ethan's cylinder has a larger total surface area.

Step-by-step explanation:

You total surface area of a cylinder can be calculated with the following formula:

Where "r" is the radius and "h" is the height of the cylinder,

 Then:

1) Total surface area of Tommy's cylinder

Since the radius is half the diameter:

Knowing that:

You can subsitute values into the formula and find the total surface area:

2) Total surface area of Ethan's cylinder

Knowing that the radius is half the diameter:

And having:

You can subsitute values into the formula and find the total surface area:

Therefore, Ethan's cylinder has a larger total surface area.

y = 3x+4

step-by-step explanation:

to find the slope

slope = (y2-y1)/ (x2-x1)

    = (-8-4)/ (-4-0)

    = -12/-4

  = 3

using the slope intercept form of a line

y= mx+b

we know the slope is 3

we know the y intercept is 4 ( the point where it crosses the y axis or x=0)

y = 3x+4
