Physics

A hollow cylindrical container has an inner radius of 7.3040 cmas stated from the manufacturer. The height of container ismeasured to be 20.50 cm. The thickness of the container walls canbe neglected. For each part, round the final answer to the correctnumber of significant figures. a) Calculate the volume of thiscylinder with the correct number of significant figures and unitsof . b) The container is filled to the top with water. The watermolecules are approximated to be spheres with a diameter of 2.75angstroms.
