Ch 22 : Surface Area and Volume (continued)
Ex.22 (C) : Nos.3, 4, 5, 6
In sum nos. 3, 4, 5 we are either dealing with a common volume of a sphere which is divided into smaller spheres or we are dealing with smaller spheres which are melted into one large sphere. This is similar to sums which you did in the previous two exercises in this chapter.
In sum no.6 you are asked to compare two spheres.
Ex.22 (C) : Nos.7 and 8
In sum no. 7 we have a comparison of the surface area and the volume of a sphere
In sum no.8 a sphere is melted into a cylinder - we will doing a lot more of these types of sums in the following exercises.
Do try the above sums.
Remember to read the sums well and keep the working out towards the end - most often, the sums do not involve so much of calculation and you see that what seems a comlicated amount of numbers can be simplified. You will save time.
All the best !
My next blog for you will be for the 11th Sept.
