Question

WILL FAN AND MEDAL

OPTIMIZATION: A wire 2 meters long is cut into two pieces. One piece is bent into a square for a frame for a stained glass ornament, while the other piece is bent into a circle for a TV antenna. To reduce storage space, where should the wire be cut to minimize the total area of both figures? Give the length of wire used for each:

Answer 1

For square and for circle

Answer 2

Can we cut more than one spot?

Answer 3

it just says cut in 2 pieces

Answer 4

so i guess just one spot

Answer 5

Sorry, this question is confusing me. Any spot would work to reduce the area. I guess you can write that you cut off half from each shape to get .5 meters. I'm not completely sure.

Answer 6

maybe the catch is that it has to minimize total area for both figures? as in each figure, instead of the whole thing together?

Answer 7

need help @Amenah8

Answer 8

Oh, this is calculus. My answer is totally off lmao. However, try this

i could do the same thing they did with the circle

Answer 16

i know XD

Answer 17

((((((((((:))))))))))

Answer 18

i just need help on the first few steps, as we are only just learning optimization

Answer 19

i'm not completely comfortable with it yet

Answer 20

i'm guessing et the circumference of the circle be x. Then the perimeter of the triangle is (7-x)

Answer 21

except in this problem it is a square, not a triangle

Answer 22

i'm confuse @Seratul

Answer 23

XD

Answer 24

The yahoo problem is a bit different from mine

@zacharydoc

Answer 28

i know i have to minimize area of each, so i need a formula for whatever i want to minimize (A=lw for square and C=pi r^2 for circle?), and i need to identify the variable that are changing and the ones that are unchanging

Answer 30

hey @zacharydoc

Answer 31

can you help?

Answer 32

and then write a formula in terms of the others if there is more than one variable and then rewrite a formula in one variable. And then take da derivative

Answer 33

i know the steps but am having trouble applying them to this problem XD

Answer 34

ok did not understand that :(

Answer 35

that's a hard problem

Answer 36

:D
