Answer 1

From the picture, the diameter of the sphere is 20 m, then its radius is 20/2 = 10 m.

The volume of a sphere is computed as follows:

$V=\frac{4}{3}\pi r^3$

Substituting with r = 10 m, we get:

$\begin{gathered} V=\frac{4}{3}\cdot3.14\cdot10^3 \\ V=\frac{4}{3}\cdot3.14\cdot1000 \\ V=4186.67m^3 \end{gathered}$
