Question:

What is the volume of a sphere whose diameter is 16.8 cm? [Use $π = \frac{22}{7}]$

Options:

2487.312 cm3

2473.812 cm3

2483.712 cm3

2483.172 cm3

Correct Answer:

2483.712 cm3

Explanation:

We know that the volume of the sphere = \(\frac{4}{3}\)πr3

We have,

Diameter = 16.8 cm

then the radius = 8.4 cm

The volume of the sphere = \(\frac{4}{3}\) × \(\frac{22}{7}\) × (8.4)3

= \(\frac{4}{3}\) × \(\frac{22}{7}\) × 592.704 = 2483.712 cm3
