Detailed Solution

 The radius of a hemisphere is 14cm14cm .
seoSurface area of a sphereQuestion Image Curved surface area of a hemisphere =Question Image of surface area of a sphere
 Curved surface area of a hemisphere =Question Image Curved surface area of a hemisphere =
Question Image Question ImageTherefore, from above we see that the curved surface area of a hemi sphere of radius Question Image  is Question Image  ∴Total surface area (T.S.A.) of a hemisphere = Curved surface area (C.S.A.) + Area of a circle formed.
 Total surface area of a hemisphere = Question Image  Total surface area of a hemisphere Question Image Substituting value of radius r Question Image in the above equation. We have,Question Image Therefore, from above we see that the total surface area of a hemisphere of radiusQuestion Image  is Question Image  So, option 2 is correct.
