What is the area in cm^2 of a disk 13.8 cm in diameter? A) If a cylinder with a cross-sectional area of 150.0 cm^2 contains 5.00 cm^3 of a substance, what is the height of the uniform cylinder? B) Assuming that the cylinder is formed from cubes and is one layer(one cube) thick, what is the volume of one of these cubes? C) How many of these cubes would be present in the 5.00 cm^3 sample? D) If the density of the material making up the cube is 1.50 g/cm^3, what is the mass of one cube?
