V = (4/3)pi * (.5)^3   ≈  .52cm^3

Hummingbirds lay eggs that are nearly spherical and about 1 centimeter in diameter.

Find the volume of an egg.

The volume enclosed by a sphere is given by the formula:
( Let d = diameter )

$\begin{array}{|rcll|} \hline \frac16 \pi d^3 \\ \hline \end{array}$

$\begin{array}{rcll} V &=& \frac16 \pi d^3 \quad & | \quad d=1\ \text{cm} \\ V &=& \frac{1}6 \pi 1^3\ \text{cm}^3 \\ V &=& \frac{\pi}6 \ \text{cm}^3 \\ V &=& 0.52359877560 \ \text{cm}^3 \\ \end{array}$
