If the diameter of a solid hemisphere is 12.6 cm, then its volume is (takе $\pi=\frac{22}{7}$):
Answer & explanation
Correct answer: option 3
We know that,
Volume of solid hemisphere = \(\frac{2}{3}\)πr3
Diameter of a solid hemisphere = 12.6 cm
Diameter= 12.6 cm
then, Radius = 6.3 cm
Now,
Volume of solid hemisphere = (2/3) × (22/7) × (6.3)3 = 523.908 cm3
