A hemispherical bowl whose radius is 21 cm is full of ice cream. Find the volume of the ice cream. (take $π =\frac{22}{7}$)
Answer & explanation
Correct answer: option 4
We know that,
The volume of Hemisphere = \(\frac{2}{3}\)πr3
Radius = 21 cm
According to the question,
Volume of ice cream = Volume of Hemisphere
= \(\frac{2}{3}\)πr3 = \(\frac{2}{3}\)π × (21)3
= \(\frac{2}{3}\) × \(\frac{22}{7}\) × 21 × 21 × 21
= 2 × 22 × 21 × 21 = 19404
