How do you find the rate of change of a volume of a cylinder?
Rate of change of volume of cylinder with respect to surface area
- Formulas: S = 2πrh + 2πr^2.
- Steps: dS/dt = 9π <– given.
- Equation: dV/dt = 2πrh dr/dt = 6πr dr/dt.
- Solve for r at the instant: 6πr + 2πr^2 = 36π
- Use r to find dr/dt in above equation: (2×3 + 3) dr/dt = 9/2.
- Put values into equation: dV/dt = 6π(3) (1/2)
At what rate is the surface area of the cylinder increasing?
32𝜋 square centimetres per second
The height of a cylinder is equal to its base diameter. Maintaining this relationship between height and base diameter, the cylinder expands such that the rate of increase of its surface area is 32𝜋 square centimetres per second with respect to time.
How do you find the height of a cylinder?
The values of the radius and volume are placed in the formula to get the volume of the cylinder. Therefore, the height of a cylinder is calculated with the help of the formula, V/ πr2.
What is the rate at which a circular cylinder decreases in height?
On a test we needed to solve the following question: A right circular cylinder with a constant volume is decreasing in height at a rate of 0.2 in/sec. At the moment that the height is 4 inch…
How do you find the volume of a right circular cylinder?
The sum of the lateral surface area and the base area of both the circles will give the total surface area of the right circular cylinder. The volume of a right cylinder is given by the product of the area of the top or bottom circle and the height of the cylinder.
Which value provides the maximum volume of a cylinder?
L`/R’ = √4 =2 value provides the maximum volume of the cylinder. , likes Maths, books, languages. The radius and height of a cylinder are in the ratio 5:7 and its volume is 550 cm³. What is its radius and height?
What is the formula to find the radius of a cylinder?
r = √(V / π h) Where, r = Radius of Cylinder V = Volume of Cylinder h = Height of the Cylinder
