The formula is the radius of the circle squared (multiplied by itself) times pi, which is a number that goes on forever and never repeats. Some people use 3.1415925, but it is most commonly considered as 3.14

This is most often written πr2 =Area of the circle where r is the radius of the circle. Using 3.14 as an approximation for π, we have Area=3.14 x r2

Is there an association between the radius of a circle and the area of a circle.. please explain?

The radius of a circle and the area of a circle are directly proportionate. This is because the area of a circle is calculated by the formula: Area = pi * radius2. Since we are using the radius to find the area, there is an association between the two.
