How do you find the radius of a sphere based on the weight in pounds?
You need to know if the sphere is solid or hollow. You also need the "density" in terms of pounds weight per unit volume. Then Volume = Mass/Density And Radius = cuberoot[3*Vol/(4*pi)]
How do you find the density of a sphere given its mass and radius?
Density = mass/ volume volume= 4/3(pie)(r^3) ***r= radius in meters** so find volume then divide mass by volume and there you go.
How do you find the mass of a sphere with a radius of 4.7 mm and a length of 3.9mm?
First and foremost, you must know the density. Mass is the product of volumeand density (m=vd). Also, a sphere is specified by its radius alone. The "length"of a sphere should represent nothing more than its diameter, which is twice itsradius.==============================Answer #2:First of all, that's no sphere, since spheres don't have 'length'.Next . . . As written, the question has no answer, simply because the mass ofa sphere doesn't depend on its size. A hundred spheres can easily all have thesame size but a hundred different masses.
How to find the volume of a sphere?
Volume of a sphere = 4/3*pi*radius3
How can you find the normal to a point on a sphere at any arbitrary point on the sphere?
It's the extension of the sphere's radius drawn to that point.
