Question:

What is the volume of the sphere whose diameter is 42 cm?(Take $π =\frac{22}{7}$)

Options:

9702 cm3

38808 cm3

10404 cm3

58212 cm3

Correct Answer:

38808 cm3

Explanation:

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
