Question

While calculating the surface area of the figure formed by combining all the three given figures, it includes:

• A. Only flat areas
• B. Only curved areas
• C. Both flat and curved areas
• D. None of the areas

Answer 1

Answer: (B)

Only curved areas

After joining all the given figures we will get a cylinder extended with hemi- spheres on both of its flat faces.

This makes the object curved on all surfaces with no flat surfaces at any part of the body.

So, the total surface area includes only curved area not the flat areas.

Hence, the answer is only curved areas.
