The table shows the area (A) of a circle for different radii r . Choose the model and its equation which best fits the situation. Radius( r ) 1 2 3 4 5 6 Area(A) p 4 p 9 p 16 p 25 p 36 p => A = 4π r 2 or A = 2π r or A = π r 2 or A = π2 r..

Framing of Formulae - We use alphabets like x, y, z etc., to denote variables. For example the length of a rectangle is denoted by 'l'. It takes different values in different rectangles. A formula is a relation between different variables formed using mathematical ..

The different arrangements that can be made with a given number of things taking some or all of them at a time are called permutations. The symbol n P r or P(n,r) is used to denote the number of permutations of n things taken r at a tim..

In a given sentence, the variables are replaced by letters and the different operations are replaced by their mathematical symbols. We now arrive at a formula. In a given sentence, the variables are replaced by letters and the different operations are replaced by th..

A molecule of a compound consists of two or more atoms of different elements joined together in a fixed ratio. Examples: CuSO 4 contains Cu - 1 atom, S - 1 atom, O - 4 atoms A chemical formula represents the composition of a molecule of the substance in terms of the symbol of th..
