How to Find the Radius of a Circle in 3 Simple Ways, Three Ways to Find the Volume of Pyramids. The volume of a cylinder is rh, where r is the radius of the cylinder and height is the height. The side length of the cube is 8 meters. Why would a cell in an animal use active transport instead of diffusion? So let me draw a cylinder over here. The cell will stop growing when there is just enough surface area to efficiently distribute the substances within the cell and the surrounding environment. At a certain point, this ratio becomes so small that the cell cannot live, so the cell must divide before this point is reached in order to return the surface area to volume ratio to an acceptable level again. We can rearrange the equation for the surface area of a cube. S = 2r2 +2rh S = 2 r 2 + 2 r h. We have established that a cell with a high volume would not survive as it would not facilitate efficient material movement within the cell and with the outside environment.
