WebNow we solve $\ds 0=f'(h)=-\pi h^2+(4/3)\pi h R$, getting $h=0$ or $h=4R/3$. We compute $V(0)=V(2R)=0$ and $\ds V(4R/3)=(32/81)\pi R^3$. The maximum is the latter; since the … Webi need to find the maximum volume of a cylinder that can fit inside a sphere of diameter 16cm. where r is its radius and h is its height. You need to differentiate this expression …

WebSep 16, 2024 · In three dimensions, maximising volume of cylinder inside a sphere (denote B 3 ( R) , wo.l.o.g centered around the origin) is straightforward. We get constraints to the radius of the cylinder via good ol' Pythagorean: (1) r 2 + ( h 2) 2 = R 2. How does one make sense of general constraints in R n? WebCylinder, Solids or 3D Shapes, Sphere, Volume. Suppose a cylinder is inscribed inside a sphere of radius r. What is the largest possible volume of such a cylinder? And what percent of the volume of the sphere does this … dyson dc39 clear bin

WebUse optimization techniques to answer the question. Find the volume of the largest cylinder that fits inside a sphere of radius 20. WebLet R be the radius of the sphere, and let r and h be the base radius and height of the cone inside the sphere. What we want to maximize is the volume of the cone: πr2h / 3. Here R is a fixed value, but r and h can vary. WebJan 6, 2007 · A closed container is made with a hemisphere on top of a cylinder. the height and the radius of the cylinder are h and r respectively. given that the surface area of the container is 20cm^2 fond all dimensions of the container (the radius and height) that will maximize the volume if the container.
