Answer 1

The answer is D) A cube with a side length of 10.

Explanation:

First you look at the measurements, we have 5. The question ask's about line M so the line goes further then the true size of our square so with the measurements it would make no sense to pick "A cube with a side of 5" with the fact that the line goes beyond the actual size of the square. Then you add the sides to get 10, if you turn the square into 3D it would become a cube not a triangle as the other answer choices state.

Answer 2

A

Explanation:

When we rotate anything, at least one part/face of it will become spherical/circular. In this case, the exterior of the shape will become circular when we rotate about line m.

A 3D shape with the above description is a cylinder. So, cross off C, D, and E. Now, when we rotate this figure to get the cylinder, the top is a circle. Since the figure is simply being rotated, the radius is not lengthened or shortened; it stays the same.

Therefore, the radius of the cylinder is still 5.

Thus, the answer is A.
