Greetings! I'm new to the forum. I am a math major with a concentration in probability. A relative wants me to find the center of gravity of the pipe. I attached a diagram below. I have no clue how to find it. I have never seen anything like this before. I know that you integrate over the x and y regions to find the center of gravity. Also, the diagram I was sent does not have a coordinate system. I would greatly appreciate it if someone could point me in the right direction.
