Find the volume of a cylinder with a radius of 6cm and height 15cm? (to the nearest whole centimeter)

For this case, we have that by definition, the volume of a cylinder is given by:

Where:

A: It's the radio

h: The height of the cylinder

We have the values:

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
