Step 1

Write out the formula for the volume of a cone


Volume\text{ of a cone =}(1)/(3)*\pi* r^2* h

Step 2

Define the parameters


\begin{gathered} \pi=\text{ 3.14} \\ r\text{ =1mm = radius} \\ h\text{ = height = 10mm} \end{gathered}

Step 3

Substitute these parameters into the formula and get the volume


\begin{gathered} V=(1)/(3)*\text{ 3.14 }*1^2*10 \\ V\text{ = }10(7)/(15)mm^3=10.47mm^3\text{ to the nearest hundredth} \end{gathered}
