Answer 1

@Michele_Laino ?

Answer 2

the volume V of a sphere whose radius is R, is given by the subsequent formula:
\[\Large V = \frac{{4\pi }}{3}{R^3}\]

Answer 3

so we have:
\[\Large V = \frac{{4\pi }}{3}{R^3} = \frac{{4 \cdot 3.14}}{3} \times {24^3} = ...?\]

Answer 4

4.186*24^3
4.186*13824=57867.264
