hi guys,
I have a 2018 iMac. I just bought an Apple Cinema Display. How can I connect the Cinema Display to the iMac and use it as a second screen?

I believe the iMac only has usb-c thunderbolt ports and the Cinema Display uses mini display port.
 
Wouldn't an Apple Thunderbolt 3 to Thunderbolt 2 Adapter work?

In this video the guy uses one of these.

If you only have one Thunderbolt port left and you want to add more accessories in the future you could also get a:
[1] External Graphics Card and plug in any video card with Displayport
[2] A thunderbolt 3 dock that has displayport

The Thunderbolt 3<—>Thunderbolt 2 adapter does not carry just Display Port signals, so it will not work.

An eGPU is an expensive solution to connect a display that old. It would be cheaper to find a decent 4K display, a 1440p or a 1080p display and move on.

Most Thunderbolt 3 docks have moved to a full size Display Port port and so you’ll need an adapter such as this - Cable Matters DisplayPort to Mini DisplayPort Adapter (DP to Mini DP) - 6 Inches https://www.amazon.com/dp/B014DV2RGG/ref=cm_sw_r_cp_tai_b5HtDbRR97BQR

The cheapest dock with full-size Display Port would be the CalDigit a Thunderbolt 3 Mini Dock
- CalDigit Thunderbolt 3 Mini Dock -Portable, Bus Powered, Non Charging, 40Gbs, Dual 4K Display Adapter, USB 3.0/2.0 and Gigabit Ethernet LAN for Thunderbolt 3 Mac and PC (Dual HDMI 2.0, Black) https://www.amazon.com/dp/B079H4WTR4/ref=cm_sw_r_cp_tai_zmItDb425XFMT

Again, a high quality 1440p 27” display can be had for $400.00. Or go for something a bit higher grade like the BenQ SW2700PT. Good luck!
