Living in Malaysia, I'm surrounded by broken English. The schooling here is done mainly in the Malay language, so many people have poor spoken English. I remember asking my colleague if my client could come at 7pm, and she replied Can. This is because in Malay, the reply would be boleh.
Indeed, representing a cell as an idealized sphere of radius r, the volume and surface area are, respectively, V = 4/3 Ï r 3; SA = 4 Ï r 2. The resulting surface area to volume ratio is therefore 3/ r. Thus, if a cell has a radius of 1 Î¼m, the SA:V ratio is 3; whereas if the radius of the cell is instead 10 Î¼m, then the SA:V ratio becomes 0.3. With a cell radius of 100, SA:V ratio is 0.03.
In this lesson students will learn how to find surface area and volume when it is necessary to subtract areas and volumes of simple plane figures and solids to find the final answer of the composite solids. 1  Finding surface area and volume of composite solids: Adding and Subtracting solids.
