Rewrite the formula using the variable x for the radius. Substitute the value of the volume found in step 2 for V and express the height of the object in terms of x plus or minus a constant. For example, if the height measurement is 4 inches longer than the radius, then the expression for the height will be (x + 4).

Simplify the equation and write it in standard form. Multiply each term in the equation by 100 to eliminate any decimals, if necessary.

(Hint: If the numbers are large, graph the function first using GeoGebra to help you find one of the zeros. Use that zero to find the depressed equation which can be solved by factoring or the quadratic formula.)

anonymous · Answer

Substitute 0 for the function notation and, using graphing technology, graph the function.

Answer the following questions:
What does the Fundamental Theorem of Algebra indicate with respect to this equation?
What are the possible rational solutions of your equation?
How many possible positive, negative and complex solutions are there in your equation?
Graph the function. What type of function has been graphed (linear, quadratic, cubic, or quartic)? Provide your reasoning and describe the end behavior of the graph.
How do the solutions of the equation compare to the radius of the cylindrical object and the x-intercept of the graph? Provide both the solutions and measurement.

can u guys help me

agent0smith · Answer

Still seems like something is missing... there's no equation or drawing or anything.

anonymous · Answer

You will need the following materials to find the volume of a cylinder:

A cylindrical object such as a soup can or thermos
Ruler or tape measure
Graphing technology (e.g., graphing calculator or GeoGebra)
Procedure:

anonymous · Answer

Measure and record the diameter and height of the cylindrical object you have chosen in inches. Round to the nearest whole number.

Apply the formula of a right circular cylinder (V = r2h) to find the volume of the object. (Note: Be sure to find the radius from the diameter measurement by dividing by 2.)

Now suppose you knew the volume of this object and the relation of the height to the radius, but did not know the radius. Rewriting the equation with one variable would result in a polynomial equation that you could solve to find the radius.
