What is the volume (in cm3) of a sphere of diameter 18 cm (correct up to two decimal places)? (Take $π =\frac{22}{7}$)
Answer & explanation
Correct answer: option 4
We know that,
Volume of the sphere = \(\frac{4}{3}\) πr3
The diameter = 18 cm
Then, Radius = 9 cm
Volume of the sphere = \(\frac{4}{3}\) × \(\frac{22}{7}\) × 9 × 9 × 9 = 3054.86 cm3
