The diameter of a hemispherical bowl is 21 cm. The volume of the bowl is equal to: (use π = )
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4. i.e. 2,425.5 cm3.
The diameter of a hemispherical bowl (d) = 21 cm
r = d/2 = 21/2
Volume of a hemisphere V = (2/3)πr3 = πd3/12
Volume = 2/3 × (22/7) × (21/2)3 = 2425.5 cm3
