Answer 1

If not then can someone explain exactly what it's asking?

Answer 2

Look at the right sphere.
The center of that sphere is point T.
Clearly, point T is in the interior of the sphere.
Ok so far?

Answer 3

Mhm, go on.

Answer 4

Ohhhhh
It's asking which one is on the outside pretty much, right? That would be H

Answer 5

Now look at segment TH.
H is a point on the surface of the sphere.
T is the center of the sphere.
That makes segment TH a radius of the circle.
Point J is on segment TH, on the radius, between T and H.
Since point J is in on a radius of the circle but is not on the surface of the circle, point J is also an interior point of the sphere.

Answer 6

So far we have seen that points T and J are interior points.
Now let's look at the other points, F, G, and H.
We already mentioned point H before. It lies on the surface of the sphere, so point H is not an interior point. The same is true of points F and G. They lie on the surface of the sphere. Points F and G are not interior points.

Answer 7

You are correct. Of the choices, only point H is not an interior point.

Answer 8

Alright, thank you for explaining, i wouldn't have understood if i was on my own xD

Answer 9

You're welcome.
