What is radius of sphere whose volume is 288 pi cube root?
volume is 4/3 pi x the redius cubed
What is the density of an object whose mass is 36g and whose volume is 12cm 3?
3 grams per cubic centimeter :D
How can you prove that the volume of a sphere is equal to the volume of a cylinder provided their radii are equal and the height of the cylinder is equal to the diameter of the sphere?
I'm quite sure this is impossible to prove, because the volume of a sphere is not equal to the volume of a cylinder with the same radius and height equal to the sphere's diameter. This can be shown as: Volume of sphere = (4*pi*r3) / 3. Volume of cylinder = pi*r2*h. Here, the height, h, of the cylinder = d = 2r. So, the volume of the cylinder = pi*r2*2r = 2*pi*r3, which obviously does not equal the volume of the sphere. The volume of half a sphere (with radius r) is equal to the volume of a cylinder(whose height is equal to its radius, r) minus the volume of a cone with the same height and radius. Therefore, the volume of a sphere is just double that. If you follow the nearby link, you can see a nice demonstration of that.
Find the volume of a cube whose edges are 8cm?
Volume = e3 where e is the edge length. So, 83 = 512 cubic cm
What is the volume of a cube whose side is 10 m (Volume length x width x height)?
Volume of cube: 10*10*10 = 1000 cubic m
