Hey,

The rq for my math ia is finding the ideal volume and surface area of lifebuoy ring. By ideal, i meant where a person won't be slipping through it and he/she is able to fit though it. I know that oi need to find the formulas for surface are and volume of a torus. for personal engagement or doing something new, i thought why not find this ideal surface area and volume of lifebuoy ring. Could anyone suggest me how to proceed from here and is this rq enough unique enough for ib not to cut down the marks?
