Question

If a rectangle was rotated about the y-axis, like the one shown below, what would be the resulting three-dimensional shape?

A. Cone
B. Cylinder
C. Pyramid
D. Sphere

Answer 1

What do you think?

Answer 2

@Sachintha I came to the conclusion of either Sphere or Cylinder?

Answer 3

It's a cylinder when rotated \(360^0\). If a circle was rotated, it will be a sphere.

Answer 4

@Sachintha Oh okay. So it's a cylinder correct?

Answer 5

Yes it's a cylinder.

Answer 6

@Sachintha Thanks!!
