As you are rotating about the y axis, Convert the equation for x in terms of y. Then differentiate it with respect to y to find the differential arc length, then integrate it from 1 to 4 about the rotation to get the surface area.

why find the arc length

the arc length rotated by 2π is basically the surface area

stiff pagoda the arc length rotated by 2π is basically the surface area

the arc length multiplied by 2pi?
