Question

The volume of solid hemisphere is 1152picm3 find the curved surface area

Answer 1

here is ur answer......

Answer 2

Volume of Hemisphere = 2/3 πr³

                          1152π = 2/3 πr³

Cancelling out π on both sides,

                    1152 × 3/2 = r³

                                   r³ = 1728

                                    r = ∛1728

                                    r = 12 cm.
___________________________________________________

Curved SA of Hemisphere = 2πr²
           
                                           = 2π × 12 × 12

                                           = 288π cm²
