Solution


Let r be the radius of the hemisphere.

Volume of the hemisphere = 18π cm3 (Given)

23πr3=18π

r3=18×32=27

r3=33

r=3 cm

∴ Total surface area of the hemisphere

= 3πr2

= 3π× (3 cm)2

= 27π cm2

Thus, the total surface area of the hemisphere is 27π cm2.

If the volume of a hemisphere is 18π cm3, then its total surface area is ___27π cm2___.
