Find the volume of a hemisphere of radius 6 cm.
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. 432π cm3.
Volume of a hemisphere = (2/3) × π × r³
r = 6√3 cm
r³ = (6√3)³ = 216 × √3 = 648√3
So, Volume = (2/3) × π × 648√3
= (2 × 648√3 × π) / 3 = 1296√3 π / 3
= 432π√3 cm³
