A cylinder has a base radius of 9 feet and a height of 4 feet. What is its volume in
pychu [463]

The volume of the cylinder will be equal to 1017.87 cubic feet.

<h3>What is volume?</h3>

Volume is defined as the space occupied by any object in the three-Dimensions. For the cylinder, the volume will be calculated by radius and the height of the cylinder.


Given that:-

  • A cylinder has a base radius of 9 feet and a height of 4 feet.

The volume of the cylinder will be calculated by using the formulas below:-

V = πr²h

V = π ( 9 )² 4

V = 1017.87 cubic feet.

Therefore the volume of the cylinder will be equal to 1017.87 cubic feet.

Would anyone be able to help me with this?

This graph has its maximum at 4. There is no minimum while the inflection is at 2, 10/3.

<h3>How to solve for the maximum of the graph</h3>

We have ( x-2²) (x-4)

x-2²) = 0, or x - 4

x - 2 = 0, x = 2

Hence we can see that the graph has its minimum at x = 4

b. The graph here does not have a local maximum

<h3>c. Next we have to find the point of inflection</h3>

To do this you have to differentiate the equation

Use the product rule of differentiation in order to solve for the solution.

(x-2)²[ (x-4) 2 (x-2)]

This would then give us

x -2, 3x -10

In both equations we have to make x the subject of the equation

X = 2, x = 10/3

Hence the point of inflection is 2 and 10/3
