Question

A hemisphere with a radius 4.0 inches use 3.14 for pi. Round your answer to the nearest thousandth

Answer 1

The volume of a hemisphere is given by:

$\begin{gathered} V=\frac{2}{3}\pi\cdot r^3 \\ \end{gathered}$

Where:

$\begin{gathered} \pi=3.14 \\ r=4 \\ so: \\ V=\frac{2}{3}(3.14)(4)^3 \\ V=133.973in^3 \end{gathered}$

Answer:

133.973 in³
