that is an abomination. nobody ever plays sports because it's a hobby. sports are not a hobby. get out of here.
Finding the area of a circle: pi*radius2 Finding the circumference of a circle: 2*pi*radius or diameter*pi Finding the surface area of a sphere: 4*pi*radius2
They both use pi:- circumference = 2*pi*radius or diameter*pi area = pi*radius2
The circumference of a circle divided by its diameter is the value of pi and pi has a wide range of uses some of which are:- Finding the volume of a sphere Finding the surface area of a sphere Finding the volume of a cone Finding the volume of a cylinder Finding the area of a circle Finding the circumference of a circle
Pi is very important for finding circumfrences and area's of circles.
singing and sports
It isn't
If you want to write a journal about hobby, just keep on writing and you will get better and better. But first you have to write what is a hobby and what is your hobby, what do you do. Examples:Music, sports , reading , writing etc

What do you mean 'finding'? Pi is the ratip of the circumference to the radius of a circle.
pi*radius2 is the formula for finding the area of a circle.
circumference of a circle = 2*pi*radius or pi*diameter
