Total surface area (including both circular ends) = 2πrh + 2πr 2 = 27πr(h + r) 4. Each solid line segment is edge, and each point at which the edges meet is vertex. If the circumference of the base of a right circular cylinder is 110 cm, then find its base area. The formulas for surface area and volume may look complicated, but they're actually quite simple when you work through them step-by-step. Firstly, determine the volume of a cone and volume of sphere using formula, volume of sphere = 4/3 πr 3 and volume of cone = 1/3 πr 2 h; Further, equate volume of a cone and volume of sphere; so that we get the radius of sphere. The graphic on this page, is designed to be a quick reference for calculating the area, surface area and volume of common shapes.
