Question:

What is the volume (in cm3) of a sphere of diameter 18 cm (correct up to two decimal places)? (Take $π =\frac{22}{7}$)

Options:

3504.58

4503.86

4530.58

3054.86

Correct Answer:

3054.86

Explanation:

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
