Hi, I'm studying for my welder Red Seal test, and i'm stumped on a question.

A cylindrical tank with a 12" (365.75cm) OD is to have a nozzle installed at 45 degrees around the circumference. From the 0 degree reference point what would be the linear measurement to locate the nozzle?

a) 4' -1/8"
b) 4' -8 9/16"
c) 6' -9 7/16"
d) 14' -1 10/16"

Thanks for reading, any feed back is much appreciated.
