Question sewing conundrum concerning cones

made some pics to explain a bit better...



so, I'm making a costume, and I need to make a dress that's shaped like a cone. I have the materials to make a rigid hoop to sew into the bottom hem to weigh it down and hold a circular shape, but I don't know how to make the cone itself.

the basic shape has to be a circle with a wedge cut out, but there are a few stipulations.

the inner circle needs to have a final circumference of 40 inches, meaning afterthe edges of the wedge are sewn back together, the circle cut out of the middle needs to be 40 inches around.

the distance between the inner circle and the outer circle (the hem) needs to be 24 inches.

basically, these are the measurements I need:
  1. new inner circumference (BEFORE CUTTING AND SEWING)
  2. new outer diameter (BEFORE CUTTING/SEWING)
  3. wedge width (how much I need to cut out to form the cone)

hopefully this makes some sense... I'm totally lost here.
