Question

You and your friend are building a snowman during winter break.You measure the snowman's head is 18 inches in diameter.What is the volumes of the snowman's head?

Answer 1

The snowman's head has the shape of a sphere.

If the diameter is 18, then the radius is 18/2 = 9 in

The volume of a sphere is computed as follows:

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

where r is the radius. Replacing with r = 9:

$\begin{gathered} V=\frac{4}{3}\pi9^3 \\ V=972\pi \\ V=3053.63in^3 \end{gathered}$
