The square shown has a perimeter of 32 units. the square is rotated about line k. what shape is created by the rotation and what is the approximate circumference of the base? circumference of a circle: c = 2πr

I think the answer is a cylinder which is form by the rotation line in the square. And for the approximate circumference of the cylinder is about 50 units. There is another formula for the circumference that I used to get that answer it is C= (pi)d. Which means you just need to multiply pi and the diameter.
