Ahula hoop measures 14 inches from the center to the outside. what is the distance around the hula hoop?

i can try and you the very best that i can.

check above link.

graphically?   well, you graph them both, the solutions is where they both intersect each other, since there are two solutions, meaning they will meet twice, or namely the linear will run into the quadratic curve twice, and where they meet, those x,y coordinates are the solutions to the system.
