Fraction of spheres in a simple cylinder
WebActivity. In this activity, students begin by looking at an image of a sphere in a cylinder. The sphere and cylinder have the same radius and the height of the cylinder is equal to the diameter of the sphere. Students consider the image and reason about how the volumes of the two figures compare to get a closer estimate of the volume of the ... WebMar 27, 2024 · Each sphere is then in contact with 12 other spheres. This means that if the volume of one sphere is V s, and you have a container with volume V c, you can fit. N ≤ π 3 2 V c V s ≈ 0.74048 V c V s. spheres in the container. The rest of the volume is "wasted" …

A cone has a circular base … WebThe formula for the volume of a sphere is V = 4/3 π r³, where V = volume and r = radius. The radius of a sphere is half its diameter. So, to calculate the surface area of a sphere given the diameter of the sphere, you can first calculate the radius, then the volume.
