Please help me! Will fan and medal! i have the answer already.
The coordinates A (0, 0), B (0, 4), C (4, 4), and D (4, 0) are graphed and connected together. What three-dimensional shape will be created when this shape is rotated about the y-axis? Provide an explanation for your answer to receive full credit.

i dont see anything

- anonymous

its just a blank white box

- UsukiDoll

it's the blue lines...

- UsukiDoll

it's probably because since all the of the points are in the first quadrant, it only regarded that area... when those points are connected I have a box, but when I drew it on here, it was not to scale.

- anonymous

oh so its a square

- UsukiDoll

yes it's a square.. the problem is the 3d part...

- UsukiDoll

I know in Euclidean Geometry assuming we have isometry (blah spelling) [ retains it shape] if we rotate it 90 degrees or 180 degrees, we still have a box.

- anonymous

so you think it would still be a cub

- UsukiDoll

I'm wondering how that box became a cylinder after rotation because cylinder is a round shape.

- UsukiDoll

jim might figure it out... this question can go anywhere.

- anonymous

thats what someone told me when they were helping me.... so i wanted to make sure it was right

UsukiDoll, think of a revolving door

- jim_thompson5910

the door panel is a rectangle
revolving that rectangle around the central axis carves out a cylinder

- UsukiDoll

what about for a box? would that cylinder also apply as well?

- jim_thompson5910

you mean a square?

- jim_thompson5910

all squares are rectangles

- anonymous

so im right?

- UsukiDoll

yup I see where this is going xD! when jim said all squares are rectangles

- jim_thompson5910

you have the right idea blahhedup101

- anonymous
