What part is giving you difficulty?
Try your best to explain what you think it's asking for. We'll see of we can set you straight.

Ordinarily I would delete a post like this, as there is no work shown, but today is your lucky day.samy4408 said:
Do you know a formula for the surface area of a sphere whose radius is given?
Can you determine what fraction of a sphere is shown in the picture?

The problem is asking you to calculate the surface of a sphere that has been cut as shown.
Can you see it tridimensional in your head?

I do know the formula for the surface area of a sphere , the problem is what they are asking for ,Mark44 said:
is it the surface of the sphere that is shown ? is it 1/8 of the total surface of the sphere ?

No. You also have to add on the new faces from the cut.phinds said:

Ah. You are right of course. I missed that they want ALL of the surface area. Still a trivial problem.caz said:

That's just the surface area of the part of the sphere. The problem is asking for the area of the partial sphere surface, plus the three other sides.samy4408 said:

It says a "solid sphere", so this is correct, IMO. If it was just a spherical surface that was cut, it would be different.caz said:
