Answer:
Radius=2.09 cm
Height,h=14.57 cm
Step-by-step explanation:
We are given that
Volume of cylinderical shaped can=200 cubic cm.
Cost of sides of can=0.02 cents per square cm
Cost of top and bottom of the can =0.07 cents per square cm
Curved surface area of cylinder=
Area of circular base=Area of circular top=
Total cost,C(r)=
Volume of cylinder,


Substitute the value of h


Differentiate w.r.t r






Again, differentiate w.r.t r

Substitute the value of r

Therefore,the product cost is minimum at r=2.09
h=
Radius of can,r=2.09 cm
Height of cone,h=14.57 cm

Answer:
Step-by-step explanation:
My drawing tool is Desmos. It can be used at no cost.
the graph will not work unless you combine -2x^ and -4x^2 to give - 6x^2.
If you try and graph it as given, you get a straight line going for quadrant 4 to quadrant 2.
But you will note that when you make the addition of the 2 middle terms, it gives you the graph that I have enclosed, which is the one you should expect. I'm wondering why you get a straight line when you try and graph what you were given.
