101 Maximum Volume of Cylinder with Surface Area 384 pi Derivatives Calculus

[@samesebor8960]

I've literally spent 2 days looking for a video like this. Thank you so much.

[@Lord_Sunday]

You saved my first year calculus course!

[@user-en6si2xn7f]

You could use second derivative to test for max/min too!

Wonderfull video, How can you find the domain of the radius, Thanks

[@MathematicsTutor]

Height cannot be negative. Radius should therefore be less that square-root of 192. Hope that helps. Thanks

Determine the maximum volume of material to be used, in cm^3 in order to produce the hollow shaft that has surface area of 10π cm^2. (Given r = 3R/4) R is outer radius, r is inner radius. Please help me 😭🙏🏻

[@manuelcastresanamartinez9882]

The radius and height of a cylinder add up to 30 inches. Find the value of the radius and height that generate the maximum volume. help pleaseeeee

[@MathematicsTutor]

maximum volume of cylinder is when diameter and height are equal, h = d = 2r. r + h = 30. since h = 2r, we can write r + 2r = 30 3r = 30 or r = 10 inches and h = 60 inches thanks

[@shwetabaisa8972]

Very helpful ....thanks a lot...

[@MathematicsTutor]

Thanks

[@lhorielynalmarez4392]

what is the unit use for the height and radius? inches or cm?

[@MathematicsTutor]

it is cm for both radius and height in this example Thanks

[@iveyl506]

I love u
