What is the volume of a cone that has a height of 7 mm and a radius of 3 mm?

use 3.14 to approximate pi and express your answer in hundredths.

So we want to know the volume V of a cone with a height h=7 mm and of radius r=3 mm rounded to the nearest hundreth. We need the formula for the volume of a cone: V=(1/3)*pi*r^2*h. Now we simply input the numbers and get: V=65.94 mm^2 and that is rounded to the first hundreth.
