WitrynaSecond, the surface area of a cylinder is: (1) 2 π r 2 + 2 π r h Now, we want to find the minimal surface area for a cylinder of a given volume. So the volume is a constant and we can the relation between the height as a function of the radius: (2) h ( r) = V π r 2 Witryna7 kwi 2024 · A right circular cylinder has height 9 cm and radius 7 cm. The cylinder is cut in three equal parts (by 2 cuts parallel to base). Concept used: Total surface area of a right circular cylinder = 2πR (R + H) (R = Radius of the base and H = Height) Calculation: Initially, the total surface area = 2π × 7 (7 + 9) = 704 cm 2 paint cost by square footWitrynaThe equation for the volume of the cylinder is πr2h. When the radius doubles (r becomes 2r) you get π(2r)2h = 4πr2h. So when the radius doubles, the volume quadruples, giving a new volume of 80.
