Find the volume of a hemisphere whose diameter is 6 cm. (Take π=22/7)
Answer & explanation
Correct answer: option 3
We know that,
Volume of the hemisphere = \(\frac{ 2}{3}\)π (r)3
Radius (r) = \(\frac{ Diameter}{2}\)
= r = \(\frac{ 6}{2}\) = 3 cm
Now Volume of the hemisphere =
V = \(\frac{ 2}{3}\)π (3)3
= V = \(\frac{ 2}{3}\)π (27)
= V = 2 × 9 π = 18π cm3
