Cross Sectional Area of a Cylinder
Cross Sectional Area of a Cylinder = π x R2 where π is a constant (= 3.14159265), which is the ratio of the circumference to diameter of a circle, while R is the radius of the cylinder. So all you need to know, to be able to calculate the cross sectional area, is its radius. The square of the radius, multiplied by π, shall give you the value of the cross sectional area.
