Question

Find the volume of each cone. Round your answer to the nearest tenth, if necessary. Do not include units (i.e. in, ft, cm, etc.). (FR)

Answer 1

Solution

Volume of a cone = 1/3 πr^2h

radius = 22/2 = 11 in

height = 22 in

$\begin{gathered} V=\frac{1}{3}\pi r^2h \\ V=\frac{1}{3}\times3.14\times11^2\times22 \\ V=\frac{1}{3}\times3.14\times2662 \\ V=2786.22 \\ V=2786.2\text{ \lparen nearest tenth\rparen} \end{gathered}$

Therefore the volume of the cone = 2786.2
