Answer 1

D

Explanation:

When we rotate this around the line m, we will get something that looks like half of a sphere, which is also called a semisphere. So, eliminate answers A, B, and E.

Now, we look at the radius. When we rotate the shape, the surface looks like a circle. The radius doesn't change, though; it is still 5. This means that the diameter, which is 2 times the radius, is 5 * 2 = 10 units.

Thus, the answer is D.

Hope this helps!

Answer 2

D semi-sphere with diameter 10

Explanation:

Rotating this along line m will give us a semi-sphere with diameter 10 ( radius 5)

It will be half of a ball
