I'm Guessing this is for a school project of some sorts as its an educational version. for something like this id probably create a surface and then cut the section away. Although i wont do it on the part for you the steps are relatively simple.
First create 3 new sketches with one being the profile and then two more for the guide curves.
Once done create a new filled surface.
then simply use the surface cut feature and your complete. if you have a go and get stuck then id be more than happy to help - but the best way to learn is to follow the steps yourself.
Hope that helps
Thanks Adam, that's all worked well.
