Linear Functions

A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

Question

Cheap paper cups
A cone-shaped paper drinking cup is to hold 100 cubic centimeters of
water (about 4 ozs). Find the height and radius of the cup that will require
the least amount of paper.
The volume of such a cup is given by the volume of a cone formula:
V = (1/3)Tr²h,
and the area of the paper is given by for formula for surface area of a cone
A = Tr/r2 + h².
(a)What Julia function relates h and r through the constraint on the
volume?
Oh(r)
h(r)
(1/3) * pi * r^2
100/ (1/3 * pi * r^2)
= 100 * (1/3) * pi * r^2
Oh(r)
(b) What Julia function would correctly represent A (r)?
OA(r)
A(r) = pi * r * sqrt (r^2 + h(r)^2)
OA(r)
pi * r * sqrt (r^2 + h^2)
%3D
pi *r * sqrt (r^2)
(c) Based on your answers above, what value of r minimizes A (r)
(d) What is the value of h for this value of r?
