There is no formula for Pi, it cannot be represented by any formula. It is a fundamental constant.
Lets call the Base of the cylinder.. Base.And use this formula on your scientific calculator.BASE = πr2This meansBASE= Pi x (RadiusxRadius)Pi is = 3.141593Radius is measured from the middle of the base to the edge of the base.
There is only one formula for pi, which is the ratio of the circumference to the diameter of a circle.
It is the formula for finding the circumference of a circle which is the same as 2*pi*radius
the circumference formula uses pi and the formula is pi (3.14) times what ever the diameter is and that's one formula i know and I'm in fifth grade
