The richmond family restaurant has several types of hamburgers on its menu. the more hamburgers their customers order, the more hamburger buns they will use.

h = the number of hamburgers ordered
b = the number of hamburger buns used

which of the variables is independent and which is dependent?

INDEPENDENT  variable  : h = the number of hamburgers ordered

DEPENDENT variable :   b = the number of hamburger buns used  

Step-by-step explanation:

Independent Variables: The type of variables whose change is NOT DEPENDENT on the change of other variables are known to be independent variable.

Dependent Variables: The type of variables whose change is DEPENDENT on the change of other variables are known to be independent variable.

Now here:

h = the number of hamburgers ordered

b = the number of hamburger buns used

The number of buns used depend upon the number on the buns ordered.

More buns Ordered ⇒  More buns Used

⇒  Used buns is dependent upon the order.

Hence, h = the number of hamburgers ordered  is INDEPENDENT.

b = the number of hamburger buns used    is DEPENDENT variable.

answer: ratio of volume of cone (with 3 times the height and equal diameter) to volume of cylinder is 2 to 1. the value of π is not used.

step-by-step explanation:

radius is diameter/2 = 4.

area of circle is π r^2.

volume of cylinder is height × area of base = hπr^2 = 3(4^2) π = 48π cubic inches.

not knowing the formula for volume of cone, i calculate it using calculus (which is for calculating things).

volume of cone is integral 0 to h area(y) dy. area(y) is π r(y)^2. r(y) runs r to zero as y runs zero to h, r(0) = r, r(h) = 0.

r(y) = r - r/h y

area(y) = π (r - r/h y)^2 = π (r^2 - 2r^2y/h + r^2y^2/h^2) = π r^2(1-2y/h+y^2/h^2)

antiderivative area(y) = π r^2 (y-y^2/h+y^3/(3h^2))

integral 0 to h = π r^2(h-h^2/h+h^3/(3h^2) - (0)) = π r^2(h - h + h/3) = π r^2(h/3) = π/3 r^2 h

volume of this cone is π/3(4^2)18 cubic inches.

= 6 16 π = 96π cubic inches.

cone has twice the volume, 96/48.

cone height is 6 times the cylinder.

ratio of volume formula: π r^2 cancels.

cone over cylinder ratio is 6h/3 to h, 2 to 1.
