A propane tank is in the form of a cylinder with two half-spheres, one on each end. The radius of the cylinder is the same as the radius of each half-sphere. What is the volume of a propane tank of cylindrical length 12 ft and radius 5 ft, correct to the nearest whole cubic foot?
Given two spheres, if the volume of the first sphere is and the volume of the second sphere is 36 , which is the relation of the second radius to the first?
