The whole surface area of a solid hemisphere with length of 7 cm radiu – InterviewSolution

1.	The whole surface area of a solid hemisphere with length of 7 cm radius isA. 588`pi` sq-cmB. 392 `pi` sq-cmC. 147`pi` sq-cmD. 98 `pi` sq-cm
Answer» The radius of the solid hemisphere =7. `therefore` the whole surface area of it =`3pixx(7)^(2) sq-cm =3pixx49=sq-cm=147pi sq-cm.` `therefore (c) is correct.
