To get the area of the base you need its radius. R cylinder radius h cylinder height To calculate the volume of a cylinder we need to know the radius of the circular cross-section of the cylinder - this is the measurement from the centre of the circle to the outer-edge. Liquid mass volume liquid density.
Liquid mass volume liquid density.
And to get the radius you can use the surface area formula and solve for r. For any cylinder with base radius r and height h the volume will be base times the height. Since the end base of a cylinder is a circle the area of that circle is given by the formula. 7 Math Instructor City College of San Francisco Expert Interview.
