Your profile implies you are using the free web version of SKetchUp. Is that correct? What operating system? 2023 is NOT an operating system.

The actual version you are using will impact the instructions you get for modeling this.

chrome?? its just the app.sketchup.com

This would be one way. Use the Pie tool to draw a semi-circle and then Push/Pull to extrude it through the roof.

You really should learn to use groups and components in your model. As it is all of the buildings and the ground are one lump of loose geometry. Components and groups are used to keep the geometry from sticking together.
