We're supposed to find a circular object and do some math with it.

Highlighter: 5in. height, 1in. diameter

2) Apply the formula of a right circular cylinder (V = PI r^2h) to find the volume of the object.
v= (3.14)(0.5^2)*5
V = 3.925

From here on, I am confused. 
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.

3) 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).
