What is the volume of the sphere whose diameter is 42 cm?(Take $π =\frac{22}{7}$)
Answer & explanation
Correct answer: option 2
We know that,
Volume of the sphere = \(\frac{4}{3}\)πr3
We have,
Diameter = 42 cm
Now, Radius = \(\frac{42}{2}\) = 21 cm
Volume of the sphere = \(\frac{4}{3}\) × \(\frac{22}{7}\) × 213 = 38808 cm3
