The problem involves calculating the mass of copper needed for a hollow spherical shell defined by specific inner and outer radii, with a given density of copper. The context is geometric and involves volume calculations related to spheres.
The discussion is ongoing, with participants clarifying misunderstandings about the geometry involved. Some guidance on the volume of a sphere has been suggested, but no consensus or resolution has been reached regarding the initial confusion over height.
There appears to be a misunderstanding regarding the dimensions relevant to a hollow sphere, with one participant initially confusing the shape with a cylinder. This may affect how the problem is approached.
babysnatcher said:How many grams of copper are required to make a hollow spherical shell having an inner radius of 5.70 cm and an outer radius of 5.75 cm? The density of copper is 8.92 g/cm^3.
Ok, so, how do I find the height? Or solve the problem without the height?
