Question

find the volume, show work and use 3.14 for pie round to the nearest hundredth

Answer 1

SOLUTION

Given the question in the image, the following are the solution steps to answer the question.

STEP 1: Write the given parameters

$r=3.h=9,\pi=3.14$

STEP 2: Write the formula for calculating the volume

$Volume\text{ of a cone}=\pi r^2\frac{h}{3}$

STEP 3: Find the volume of the cone

$\begin{gathered} Volume=\pi r^2\frac{h}{3} \\ By\text{ substitution,} \\ Volume=3.14\times3^2\times\frac{9}{3} \\ Volume=3.14\times9\times3=84.78 \end{gathered}$

Hence, the volume of the given cone is 84.78
