Answer 1

Hi.

Good question and Keep Progressing

Here is your answer---

__________________________________________


Given---
           Radius of the Hemisphere(r) = 14 cm.
        
According o the question, we have to Find the Surface area. Surface area can be Curved surface area or Total surface area,

Note ---{ For the Hemisphere, curved surface area and total surface area are different but for the sphere these are same.}
   
For Total Surface area,
       
          Total Surface Area = 3 x pie x r^2
                                         = 3 x (22/7) x 14 x 14
                                         = 1848 cm^2



For Curved surface area,
   
    Curved Surface Area = 2 x pie x r^2
                                        = 2 x (22/7) x 14 x 14
                                        = 1232 cm^2
