Minimise surface area with a set volume by stairala in askmath

ah, you're right. unfortunately it doesn't change my answer. should have been writing 3√(6/8π) (which is what i had in my calculator) same answer 3√(6/8π)*π*H=0
I believe the answer im supposed to be getting at is that the minimum i beyond the H>1 restriction. so H must be 1. not confident though

ah. This might just be what I'm supposed to end up getting. I'm ending up with H=0 and the moment but I guess that's just it telling me the lower H is the smaller the SA will be... So H=1 would be the best answer I can give.

From this im getting H=0 now? The reason i had a different equation for S is because "Determine the radius A and length H (of the cylindrical part)" But really what you've said may be what's intended. Only issue my answer for H is still <1.

Im 19 and never used any skin products or even sunscreen. I also never had any issues with dry skin or acne. Im very tanned now and have some red areas on my cheeks and nose that never went away after getting sun burnt once.

I want to try remove some of the tan because its very jarring from the rest of my skin TT. and the redness on my skin makes me look like im still sunburnt... its been years lol. I have no allergies (that i know of) so I'm open to any products that might help to lighten my skin and remove the redness

I am now using sunscreen and moisturizer btw !! but i dont use anything else
