WebAug 4, 2024 · If you think of the derivative of the volume as lim h → 0 V ( r + h) − V ( r) h, and interpret it geometrically, it becomes easier to see why it should equal S A ( r). However, lim h → 0 S A ( r + h) − S A ( r) h has no obvious geometrical significance. – Akiva Weinberger Aug 3, 2024 at 22:50 3 WebSep 27, 2024 · Formulas: S = 2πrh + 2πr^2 V = πr^2h Steps: dS/dt = 9π <-- given d/dt (2πrh + 2πr^2) = 9π dr/dt (2πh + 4πr) = 9π (2r + 3) dr/dt = 9/2 <-- divide by 2π Equation: dV/dt = 2πrh dr/dt = 6πr dr/dt Solve for r at the instant: 6πr + 2πr^2 = 36π r = 3 Use r to find dr/dt in above equation: (2x3 + 3) dr/dt = 9/2 dr/dt = 1/2 Put values into equation:
WebThe formula for the volume of a cylinder is height x π x (diameter / 2)2, where (diameter / 2) is the radius of the base (d = 2 x r), so another way to write it is height x π x radius2. Visual in the figure below: First, measure the diameter of the base (usually easier than measuring the radius), then measure the height of the cylinder. WebThe volume of cylinder formula (Volume of the tank), V = πr 2 h V = (3.14)(25) 2 (120) = 235500 cubic inches. Therefore, the volume of the given cylindrical tank is 235,500 cubic …
