Find the volume of the cone. Use 3.14 for

π\pi

π

Please round your answers to the nearest hundredth (two decimal places)

Step-by-step explanation:

This question is about using the formula of the volume of a cone.

The formula of the volume of the cone of radius r and height h is given by

So, let us suppose we have a cone of 3 centimeters of radius with a height of 10 centimeters. Then its volume is given by

which is about 94.2 cubed centimeters.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2
